We do not prevent the installation of our products on Windows 7 32-bits, XP or Vista. However, we no longer support these operating systems and it is possible that our products do not work for every configuration (to the best of our knowledge, we have a small customer base still using our products successfully on Windows 7 32-bits, XP and Vista).
We no longer provide updates or quality assurance efforts on products running under these operating systems. As such, these products are offered “as is” for Windows 7 32-bits, XP and Vista. If you are using one of these, you can download the last 32-bits versions published here.
It all boils down at ensuring the best quality products for the vast majority of our customers. We use as a reference the Microsoft Windows End-of-Mainstream-Support date. Therefore, Windows XP (published in 2001), Windows Vista (published in 2006) as well as Windows 7 without Service Pack 1 are no longer supported (Windows 7 SP1 support ended in July 2017).
Note: this approach is subject to change without notice.
