During the installation of Diskeeper, you may be asked for a Product Activation key. Generally a license file accompanies the Diskeeper and V-locity software when you download it. The license files are distinguished by their extensions; .dal for Diskeeper. these Activation Key’s (29-digit codes) are no longer supplied for home use purchases. Since there is no license key, your download should include a .dal license file, if it is needed for activation. You may already have such a license available for download from your Condusiv Account.

There are two methods by which to utilize these Diskeeper license files.

Where Diskeeper is already installed in trial mode, you can copy the appropriate Diskeeper license (.dal file extension), paste this file in the C:Program FilesCondusiv TechnologiesDiskeeper folder and then lastly restart the Diskeeper service from within your Services.msc list or with a reboot of your machine.

Where Diskeeper is not yet installed, you can use the Diskeeper license file (.dal file extension) to make your installation a FULL INSTALL. To do this, copy the Diskeeper license file into the same folder location where your Diskeeper install (.exe file) is. So long as the license and the executable are together when you start the installation, the license should be recognized and a full installation will be accomplished.

If you do not have a current Maintenance or Upgrade Assurance contract, you can purchase a subscription to new DymaxIO easily online, from your favorite reseller , or contact your Condusiv Account Manager.

If you own a single license of Diskeeper, it may be that you did not properly receive your license file or it was not present in the directory/folder that you launched the install of Diskeeper. In that event, you can visit your Condusiv Account and re-download the install package (the license should accompany this and will be a file with a .dal extension). Now, copy that license file into the C:Program FilesCondusiv TechnologiesDiskeeper folder and then either restart the Diskeeper service from the Serices.msc list or simply reboot your system.

If you are using Diskeeper Administrator, you can convert a trial license through the License section. To do this, open Diskeeper Administrator, select the Manage Computers and Software tab and then select the Manage Software Licensing section. Within this section, click on the Actions button to use the Upgrade Try and Buy Computers option. This should convert the trials to full.

Where an upgrade is purchased and installed, as its name suggests, it must be installed over the top of a qualifying older version of Diskeeper unless other instructions are specified. The Diskeeper upgrades support upgrading from versions of Diskeeper only 1 to 2 versions prior to what you’re installing. (Example: Installing a Diskeeper 18 Upgrade would support installing over Diskeeper 16 and Diskeeper 15 but not Diskeeper 12 or prior). If you are installing an upgrade over a version that is 3 versions old or older, this could result in the installation coming out in trial mode.

If you find that to be the case, please purchase the current version of Diskeeper/SSDKeeper. If you need further assistance, notify our Customer Service section to assist you with the details of that purchase.

If you are installing the upgrade over a qualifying version and yet it still arrives in trial mode, check first to see if a license file (.dal) accompanied the download of your software purchase. If not, check your Condusiv Customer Portal to see if the license file is available for download. If it is not, then please notify our Technical Support section.

The following products can interfere with the download of your purchased product. It may be necessary to disable the following products for the duration of the download:

Firewall products
A firewall monitors the data traffic passing through the firewall to protect the network behind it from unauthorized access. This means that a firewall can also prevent downloads from unauthorized Web sites.

Antivirus products
This software searches for, blocks, and removes computer viruses, worms and other unknown and possibly malicious programs. An antivirus product can therefore also block a download even if there are not any viruses in it.Occasionally these may also affect your ability to download the software:

Download monitoring products
This is special software that will monitor downloads of any kind. These products can also interfere with or stop a download.

Screen savers
In some cases, screen savers can interfere with downloads. We recommend that you switch off your screen saver while downloading your product. Once you have downloaded your software, don’t forget to enable your firewall and/or antivirus software.

If your software delivery is via the Download Manager program (the file begins with a DM_(character string), and he download process hangs or doesn’t finish, try downloading it to a different computer if you have one. If not please contact Customer Service for assistance.

In the event you still cannot download your installation, please submit a Customer Service Request.

Log into your customer account and download the software zip file(s) and access your license key(s).

  1. Install the software
  2. Input your license key
  3. That’s it! No reboot is required.

The software can also be installed via the Management Console to deploy it remotely across your network.

At the time of purchase, we create a Condusiv Account for you where we save a back-up copy of your software. Your software is saved for a period of approximately three years.

When you download your software you will be given a choice to either run or save your software.

The files that should be saved to a CD are Diskeeper18_ProductName.exe & ProductName.DAL. These files should have been downloaded and saved to a location that you specified. Use the saved files to burn a CD as a back-up for yourself. (ProductName = Home, Professional, Pro Premier, Server)

If you downloaded your software but the file has an .efw file extension and won’t install, simply change the file extension from .efw to .exe and double click on the file to run it. This will start the installation of the software on your computer.

Some brands of antivirus and security products change the file extension of an executable file from .exe to .efw when such files are downloaded.

In this case, please check your Condusiv Account.

Product Activation

The Product Activation Key is a set of numbers and letters that uniquely identify your Condusiv Technologies software from any other Condusiv Technologies software. It is also referred to as a License Key. For retail packaged product (CDs/DVDs) this key is provided for you to manually enter into the software during installation or shortly thereafter. For electronically delivered software (internet download) some of our products will provide this 29 digit key for you on the purchase receipt and again in your Condusiv Account so that you can enter it manually, while other products have the key integrated into the software for you, eliminating the need to manually type it in.

The software activation process uniquely identifies a given computer via proprietary mechanisms (a computer ID). This computer ID is bound to the product activation code (software ID) provided with your software (i.e. the license key) at a private and secure Condusiv Technologies server.

NOTE: The computer identification process (computer ID) does not ever collect or transmit any data that can be used to identify an individual or company. The software ID (product license key), when delivered embedded within an electronic download also never contains personal or company information.

If the software prompts you to activate you must do so within a 30-day grace period. A full 30 days are provided to make this process as unobtrusive as possible. During this time period you will receive occasional notifications reminding you to complete the process. Failure to activate the software within 30 days will cause it to cease to function. If disabled, the software can still be activated at any time afterward.

Activation enables all uses currently allowed under the product license agreement pertaining to the product.

Not at this time. Also note that activation is only required when prompted.
Yes. If prompted to activate, the computer will need to access the internet at some point within the 30 day grace period to complete the process. Please note that phone activation is not available at this time. Other options are available for computers that do not have internet access, such as the Manual Activation process (found within the Activation window).

No, it does not check every time it runs. It will check when you first activate it and then periodically. We understand that some systems, especially laptops, may not always be connected to the internet, so the check has to fail several times before it actually fails.

If you have re-installed your software and you received an activation error stating that: You may not have an internet connection You have an “Invalid license” You have “Exceeded number of activations permitted per license” Please submit a Customer Service Request and we will be happy to help you further.

When so prompted, activation will restrict the number of computers you can install the software to. If you have purchased 1 license, you will be able to install the software on to 1 computer. If you have purchase 5 licenses, you will be able to install the software on to 5 computers, etc… Your purchase agreement/receipt will describe the number of licenses you are entitled to use.

Diskeeper is licensed by Operating System (ie. one license per Operating System ). Diskeeper 18 Home can be installed on up to 3 computers. For all other editions, if you would like to use Diskeeper on a second or third computer you will need to purchase more licenses.

This depends on how many changes are made, and specifically what changes are made. If you are prompted to reactivate, the process will work the same as your initial activation procedure. In many cases the software will recognize only a few/minor changes have occurred and you will need only to follow the same procedures as before. If there are complications you can submit a Customer Service Request for assistance.

If you uninstall and then re-install the software (on the same computer with no changes) you will have to activate again if you were required to activate on your initial install. This process will behave as seamlessly as it did before. Note that days counted towards your 30-day grace period are cumulative and will continue to be deducted.

Updating the software (installing an incremental “build” update – e.g. updating v2.0.100 to v2.0.101) will not require re-activation. In some rare cases, upgrading (e.g. v2.0 to v3.0) may require activation.

If you upgrade the operating system or restore the operating system using special software you may be required to reactivate. In cases where the operating system is upgraded (e.g. upgrading Windows 7 to Windows 10 or Windows 11), we recommend uninstalling the software prior to upgrading, and then a reinstalling the software afterwards.

Yes, however this process can be automated. In many cases, you will have an option to receive an electronic download with product activation keys already embedded, mitigating the need to manually type in the key.
Volume license customers have to activate every copy of the software. Volume License customers are however provide additional “padding” which allows more product activation allowances than actual purchased licenses to account for system changes, system retirement, and future growth.

Volume license customers should contact their Condusiv Technologies Authorized Reseller or customer service representative if they have questions or additional needs.

Condusiv Technologies products offer automated mechanisms for activation (e.g. via Group Policy, during installation, etc). See product help files for more information on automating activation.

Yes. Activation is designed only to guarantee that the software is genuine. It does not ever collect or transmit any personal data. When required, activation is mandatory.

Registration is a completely separate and optional process designed exclusively for customers who want to register for product support and to receive information about product updates and other special offers from Condusiv Technologies. If you purchase from our online store, you product is automatically registered for you.

Note: Activation and Registration data are entirely separate. See the Condusiv Technologies privacy policy for more information.

The activation process will allow you to transfer activation from your original computer to another computer. You will need to first uninstall the software from the original computer. After the uninstall is complete you can install the software onto the new computer. You will be required to reactivate the software on the new computer. If you no longer have access to the original computer, you will need to contact customer service to complete the transfer process.
Condusiv Technologies is continuing to expand globally. This expansion is taking Condusiv Technologies products into new regions where laws regarding intellectual property (IP) are lenient or non-existent. To effectively operate in such new regions, and guarantee the quality and legitimacy of the software, activation technologies are being introduced. The design of the technology will incur little to no effort for most of Condusiv Technologies’s existing loyal customer base.

You may be required to reactivate if you change one or more hardware components that make up your ‘Hardware ID’. Our software is typically smart enough to detect slight hardware changes and allow reactivation.

Diskeeper uses dkservice.exe to process the activation request. It will need to communicate to a secure Diskeeper Activation Server located at The connection uses TCP port 443 (also known as HTTPS – a secure transmission). If you have a firewall that queries or blocks this communication, you will need to adjust the firewall to allow this. It is a one-time action, unless you are required to re-activate due to system hardware changes.

Where Diskeeper is installed as part of a corporate image, the activation process should still occur automatically. During the initial install to the base image, you will be prompted to activation Diskeeper. Once done, you can then roll out these images to other systems naturally. When Diskeeper opens within the new system it’s installed to, it should recognize the new environment and then attempt to activate on its own. Should the system that the image is rolled out to, not have internet access however, it’s possible that this automatic activation will fail and therefore, you’d need to attempt a Manual Activation or utilize a program such as Diskeeper Administrator to facilitate the activation process.

Should you have any difficulty, please submit a Customer Service Request for assistance.

During a standard installation of Diskeeper, you will find an option to Activate silently and automatically. If you’d prefer that this doesn’t happen, you can uncheck that option. Where Diskeeper is being installed via command lines, Diskeeper will also attempt to activate when defined to run as an “unattended installation”. If you’d like to avoid this, you can include the syntax SILENTACTIVATE=0 as part of your install command (EXAMPLE: setup.exe /v /s/qn SILENTACTIVATE=0).

In most cases, Diskeeper product activation will take place automatically with little or no intervention from you. However, if you are installing Diskeeper on a computer that does not have an Internet connection; you will be prompted to activate Diskeeper manually. Manual activation can be done from another computer, but it must be connected to the Internet.

Manual Activation Instructions

When activating Diskeeper automatically is not working, you may want to choose to activate manually as follows:

1. Once Diskeeper is installed, it should prompt for activation after it is first opened.
2. From that activation pop-up, select the option to Activate Diskeeper Manually and click OK.
3. Highlight the code displayed and copy this to a document that can be saved to a USB thumb drive.
4. Take that USB thumb drive to a computer to has internet access and plug it in.
5. From this new machine, open Internet Explorer and go to That should open the page below:

6. Next, open the document on that USB thumb drive, in order to retrieve the code and paste that code into the Step 1 field in the screen above.
7. Select the ACTIVATE NOW button.
8. After that, you should receive an even longer string of code in Step 2.
9. Copy the code from Step 2 and paste it back to the USB thumb drive.
10. Now, taking the USB thumb drive back to the original system with Diskeeper, you can copy that newer code and paste it into Step 3 of the Diskeeper Activation pop-up to activate your product.

Your Diskeeper software should now be activated on your machine.

Please note: If you still encounter difficulty with this or if this fails, please submit a Customer Service Request department.
