Some weeks ago I tried to update to a new version of Opus D. The update failed so I have no Opus-D. I also have no Explorer as I had set Opus D to replace Explorer as my file manager. What do I do to retain control of my computer? Thank you for your helps.
What type of failure did you see? Was there an error message? What did it say?
Have you tried downloading the latest Opus installer (for the version of Opus you're trying to run, e.g. Opus 10 or Opus 11) and running it to see if that works?
If that still doesn't fix things, does the uninstaller work?
Thank you Leo; I followed the link you gave to install again and everything worked
