After setting a custom feed in Web Platform Installer when trying to set up mojoPortal the program crashed with the error ProductId NETFramework4 not found
:
When trying to launch the program again the same error happened upon launch.
I tried re-installing the program but the problem remained.
The fix that worked for me was to delete the configuration file webpi.preferences
found in the folder:
C:\Users\UserName\AppData\Roaming\Microsoft\Web Platform Installer
To get there you can:
Press: Win + R
Type: %APPDATA% Enter
And then navigate to the folder mentioned above and delete the preferences file.
