This is a shell extension and the DLL is used by the Explorer process. There are two scenarios: 1) Uninstall - no file is actually "replaced", simply deleted. 2) Upgrade - the DLL is replaced by a new version.
The Restart Manager correctly identifies that the DLL is in use by Explorer and offers to close it. If I choose to close it, everything works fine - The Explorer is closed, then restarted at the end of the install process. If I choose not to close it at this time I expect a prompt to reboot the machine at the end. I don't get one. So the old version of the DLL is still loaded by Explorer, preventing the new version from showing up. The thing gets a bit more complicated because the shell extension gets loaded in other processes that use the shell (pretty much every app that has a FileOpen box). That's why I want to rely on the Restart Manager to do its thing instead of trying to make a custom solution specifically for Explorer.exe.
