? There was no version 9.4.

Anyway, try following the guide to [manually removing Explorer Replacement settings](https://resource.dopus.com/t/how-to-manually-remove-explorer-replacement-settings/3646/1).

That should clean up any Explorer Replacement registry settings left over from installing earlier versions of Opus on Windows 7.

After doing that, reinstall 9.5 and everything should work again.

If it doesn't, does the control panel work if you uninstall Opus?
