I know this must be something silly, but so far I was unable to figure it out...
I'm installing all the files into folder that already exists (was previously installed by other installation application) and already has some files in it. My app is just a DLL to be part of the other application.
Some files are also installed into new subfolders that are added by my installation under this pre-existing folder. None of the files I'm installing replaces any of the pre-existing ones, it's all just added.
None of my files of folders are added using custom action, it's all AI (Files and Folders).
When I install the application everything works great. But when I uninstall (from Control panel / Add-Remove programs) all the new files files are left behind - they are not being removed.
Any ideas?
Thanks.
