Nope this is not the issue, because as I mentioned, the sxs folder and files for both versions do exists after the install and if it was like this article then the older version would be gone.
So the files exist, but the app can not find the assembly, so this implies that the system no longer has that version registered even though the files and folders are intact. So again could the MsiUnpublishAssemblies and MsiProvideAssembly actions be causing the issue, or could there be some kind of conflict before the 2 versions that are causing the register of the new version to somehow override the registration of the older version?
