I wanted to install Service pack for Visual Studio 2005 on my Windows Vista based computer. But when I start the Windows installer service it gives me error saying “Windows installer service cant start Error 193:0xc1”.
I tried installing any other setup with .MSI but that too failed with an error “The Windows Installer Service could not be accessed.” I’m just unable to install anything with MSI.
To find out some info about this errors and problems I went to check Event Viewer log where I found this:
The Windows Installer service failed to start due to the following error:
Windows Installer is not a valid Win32 application.
I don’t have any idea what to do to get rid of these errors. Can anyone help me out please ?
