Got a strange problem here with Microsoft Project 2003 Pro On uninstall its looking for the original file that was used not the cached version. We get error 1306, this is using windows installer 2. If we rename the cache file to the file its looking for prjproe.msi it then uninstalls fine. We could do a script to rename it before its uninstalled but why should we is this a Microsoft bug or summin , anyone know what determines the file name of the cached msi ?
