Once installed and serial number in, the splash screen (forest) appears and just after i have a box "Problem report for Lightroom" and "quit unexpectedly"
I tried uninstalling it and reinstalling, i tried restarting computer, i tried twice with lightroom chat support but no success.
What is the issue please ?
