Inflectra Customer Forums: Upgrade from v3.2 to v4.0 does not work with .NET 4.5 installed. (Thread) I am trying to upgrade our installation of SpiraTest from v3.2 to v4.0. Everything seems to go well until at the very end of the installer is says that .NET Framework 4.0.30319 must be installed. Our server has been updated to .NET 4.5 (4.5.50709) which was required for other applications and it is my belief that it is backward compatible with .NET 4.0 applications. How can I get around this issue? en-US(C) Copyright 2006-2026 Inflectra Corporation.support@inflectra.com/Computers/Software/Project_Management//Computers/Software/Quality_Assurance/KronoDesksupport@inflectra.comhttp://www.inflectra.com/kronodesk/forums/threads120/Support/Forum/spiratest/issues-questions/547.aspxthreadId=547Dominic McKeown (dominic@ramm.co.nz)Upgrade from v3.2 to v4.0 does not work with .NET 4.5 installed.

This was fixed in the v4.0 installer, but because you are doing an update, the issue is that the part when it uninstalls v3.2 uses the older installer which does not have the fix. If you open the following registry keys and locate the Version string and change it from 4.5.50709 to 4.0.30319 it will fake the installer into thinking that .NET 4.0 is installed. Once you are done, you can change it back.
