Upgrading Files in NEEDSUPGRADE-Mode

[sq-rom]

When I upgrade an older Installation by running a newer setup with the same product code but with a different revision code, I met the problem that my files are not updated.

I made sure that my files have changed in size and edit date but after the installation the file is still the same as it was before.
I also have the line with install files before apply install

Is that default behavior of MSI? In the help it says that older files are replaced if they already exist on the target.

It sounds like you might be wanting to use a patch. With an upgrade, the previous version should be removed and the new version installed.

Does your setup go through a "previous version uninstall"?

How was your project created, based on what template?

I found the mistake. I didn't run the uninstall of the previous version as you said.

Maybe the Patch solution would be better in this case.
thanks
