I had a problem with lightroom 6 and windows 10. I moved back from window 10 to 7 due to a driver problem. Although my PC works agqain, LR6 doesn´t.
I then tried to uninstall LR 6 and reinstall it again. I received the following message: configuration error, uninstall and reinstall the programm again, error 1. I tried to remove LR 6 with the Adobe tool (adobe creative cloud cleaner,) but that didn´t work, and the same message came back.. Has anyone an idea how to solve this problem?
What do you mean you went back to Win 7 from Win 10? Did you use the built in Revert to previous version of Windows or did you have a backup image of Win 7 that you reloaded.
It has been my experience of the years that Upgrading to a newer version of Windows over the top of an older version never really works. And then trying to go back to the previous version of Windows just mucks up the works even worse.
thanks for your response: I used the built in revers procedure to previous Windows version
