Since I had a sudden breakdown while saving on Lightroom, it refuses to start again. It will open but during startup but it will eather refuse finishing startupp because " an other program is using the ***.lrcatalog" Before that LR will start opening until it reaches this message. No other open application is to be found.
If I try to start from a singel image file it even shows the catalog image frames and start loading upp the files but stops before finishing.
If I try to start from an other catalog the result is the same. The Creative Cloud lets me download and unzip installation files but they will not install. I can´t uninstall the existisng LR with the uninstall tool in Windows.
