I add a custom action before system updates in the Uninstaller. The custom action will invoke an exe file which is installed together with other files.
The uninstaller will work properly in Windows XP, Windows 7, Windows 10(64bit). However, in Windows 10 Home(32bit), it will fail and report "Error 1721: There is a problem xxx"
I try to execute the exe file manually in commandline and it can run without any problems.
