I am trying to uninstall WebPI v4.0 from my computer. When I running msiexec with full logging, the log includes the following:
1: IISCA IISExecuteCA : Begin CA Setup 1: IISCA IISExecuteCA : CA 'ExecuteRegisterUIModuleCA' completed with return code hr=0x80040154 1: IISCA IISExecuteCA : CA 'IISExecuteCA' completed with return code hr=0x80040154 1: IISCA IISExecuteCA : End CA Setup CustomAction IISExecuteCA returned actual error code 1603 (note this may not be 100% accurate if translation happened inside sandbox)
How can I fix this? I am trying to update to WebPI 4.5, but that fails for the same reason.
Maybe the following information helps:
Installed WebPI v4.0 as Windows 7. Then upgraded to Windows 8. Now trying to uninstall v4.0.
