Remove Files does not work in Windows Installer
Posted on 2010-09-09
I create installers that install revisions of software and files that coexist with previous installations. I discovered that two unversioned files from previous installations were incorrect. The only way I could find to always overwrite them was to add entries to the MSI's RemoveFiles table. This did not work, even though the installer log said it did:
Action 14:18:27: RemoveFiles. Removing files
RemoveFiles: File: IntelliRupter-2.3.3.zsd, Directory: C:\Program Files\S&C Electric\Products\IntelliRupter\HMI\2.3\
RemoveFiles: File: IntelliRupter-2.2.9.zsd, Directory: C:\Program Files\S&C Electric\Products\IntelliRupter\HMI\2.2\
Action 14:18:27: CreateFolders. Creating folders
InstallFiles: File: IntelliRupter-2.3.3.zsd, Directory: C:\Program Files\S&C Electric\Products\IntelliRupter\HMI\2.3\, Size: 33129
InstallFiles: File: IntelliRupter-2.2.9.zsd, Directory: C:\Program Files\S&C Electric\Products\IntelliRupter\HMI\2.2\, Size: 33128
When I look at the appropriate directories, the older files are still there.
Has anybody had similar experiences, or does anybody know of an easy way (VS 2005, Windows Installer project) to force always overwrite on unversioned files?
