Dear Christ23,

the error comes from InstallAware application or it happens during your setup execution?

Dear Francesco,

the error came during installation. But i could fix it. Just commented out the remove-msi-part, running setup, and then deinstalling again. Think i had some struggling inside my msiCode.

Dear Christ23,

By the error seems you are trying to update, reinstall or install an additional feature of a Windows Installer setup from a different version of the source setup.

If you executed a repair of your installed package before uninstalling it and it worked ... I really suspect that there are some inconsistencies with the packages.

In fact, if you search in Windows Installer error codes for that error it is suggested : "Try the installation again using a valid copy of the installation package".

Anyway ... I am happy that you solved.

There is another possibility. If you're testing your installer, doing different builds with the same version number without uninstalling in between, this will also cause this error to pop up. Basically, it appears to be looking at some information in your setup, sees that its the same version as what's already installed, but things don't match up between the two.

Does this seem to describe what you're doing? If so, then you either need to uninstall before running the newest iteration or you need to change version numbers between iterations.
