Problem description:
We have a setup where we require to install the .NET Framework if not already installed.
This happens in the PRE-INSTALL stage to prevent the AdvancedInstaller Setup blocking the installation of .NET Framework.
In the past, the installation also worked in the FEATURES stage, but we had to put it to PRE-INSTALL after using newer version of the .NET Framework which began to be blocked by the main setup.
It worked all fine with the .NET Framework 4.5 web installer.
Due to an update, we require an installation of .NET Framework 4.6 for the application, only to run into the same problem as in the past - the installer of .NET Framework is being blocked my the main setup.
This problem only occures on Windows 7. We have also tested it with Windows 10 and it works fine.
Environment:
Setup was created with AdvancedInstaller v13.7
Windows 7 SP1
