Hi Peter. Thx for your answer, but I can't do that because I need the files to be removed _only_ when uninstall (not updates) and I have <RemoveExistingProducts After="InstallInitialize"/>. And as I described here: http://windows-installer-xml-wix-toolset.687559.n2.nabble.com/BUG-limitation-in-WIX-MSI-No-way-to-distinguish-between-an-uninstall-and-an-update-when-lt-RemoveExi-td5776494.html when REP is after InstallInitialize, it can't be done with Component conditions.
So I need a CustomAction which deletes the file and can be conditioned to happen only when real uninstalls. Because of that I got to the code below, which doesn't work. Can somebody pls help me?
