The File 'DfxInstall.dll' is not marked for installation

Hello,

I would be very thankful if someone could help me out here.

I am on Windows 11.

I had installed FxSound earlier (latest version 1.1.20.0). Later I uninstalled it using a 3rd party uninstaller software. The devices were still there in device manager so I uninstalled them manually. Also deleted some registry keys (I dont remember which ones).

Now my system seems free from FxSound. When I try to install an older version I get a message that a newer version is already installed and when I try to reinstall 1.1.20.0 I get the message “The File ‘DfxInstall.dll’ is not marked for installation.”

I searched my whole system for any files with the names fxsound etc and found none.

Please help with how to go ahead.

I tried extracting and then running the msi too.

I just wanted to inform that running the below troubleshooter from microsoft uninstalled it properly and I could successfully reinstall the latest version.

Good afternoon,
Apologies for my late response; I was, quite simply, asleep.
Good to hear you managed to fix the issue on your own, thanks for letting us know.
