About a week ago I had to reinstall windows XP pro sp2 from an original OEM Sp2 CD. The re-install went OK.
When I came to do updates it bombed out with a failure when trying to update to Windows 3.1 installer.
Have possibly solved that problem as the version of msi.dll is 3.1 and windows udpate no longer tries to install it.
However no files with the .msi extension will install giving the *.msi is not a valid Win32 application.
Have tried to use a file to update the registry keys but that won't complete.
I need to install php and mysql on IIS5.1
Also all windows updates fail after the install of win installer 3.1 - 93 updates in total
