Obsolete Versions

Obsolete perpetual license versions of our products are available to registered users. If you need to download an old version you are licensed for, contact us directly and we will send you a download link.

Download an evaluation copy from the Downloads page.
Install the Evaluation copy in the same location as your old copy.
The evaluation copy should find your existing registration information and register itself automatically. In rare circumstances you may have to re-enter your registration information.
You do NOT need to uninstall the previous copy of the product

When we release new major versions of our products - that contain significant new features - we declare the previous version obsolete.
We provide links to obsolete versions on request. The versions can be downloaded and unlocked using your old registration codes but these codes will NOT unlock the new release.
You can continue to use the obsolete product indefinitely but we will charge a subscription fee if you wish to begin using the new release.

Choose Programs and Features from the Windows Control Panel.
Choose the program you wish to uninstall from the list of installed programs and press Uninstall.
Please note that you do NOT need to uninstall old versions of our products in order to update to new versions.
