There isn’t much information in the image as there are lots of errors as such but no detailed information on individual errors.

Unfortunately this looks like you need someone with a working knowledge of tracking/fixing system errors.

  1. search the registry for those names for instances of either of those.
  2. he gives a registry path “HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\BazisPortableCDBus” this may have the driver location.

I tried a search on how to uninstall WinCDEmu Portable, which turns up a lot of hits.

But many of those say it is a run once thing (e.g. portable) and doesn’t install.
