Unable to update (or uninstall) Mediainfo

[Martin2108]

I cannot update (or uninstall) Mediainfo (installed is 17.12). There is no response. Last update (17.12) was via PatchMyPC in December.
The pogram works as expected, but can't update or uninstall (manually or via PatchMyPC)
Any known problems or any hints how to poceed. System is Windows 10 1709 16299.309

Not that we are aware of. What do you mean there is no response? What happens if you manually run the installer that it doesn't work?

Manual update or uninstall does also not work. The installer (or uninstaller uninst.exe) prompts for user privileges and ends without any note.
Seems this problem is not related to PatchMyPC.
I also opened an issue at MediaArea; they suggested to manually delete "C:\Program Files\MediaInfo", which I did. Then I could reinstall / update MediaInfo 18.03. It seems to work as expected (even via the file explorer dropdown), but uninstall is not possibly. The uninstaller asks for user privileges and then ends without any note. I cannot see in taskmanager any related piece.
Thanks for help
