Lightroom (CC) on windows 8.1 64bit is not starting after successful installation without any message
I have updated with my creative cloud abbo Photoshop cc 2014 and Lightroom. The update has installed the new Lightroom in parrallel with my existing lightroom 5.71 (64bit). This is still working. I have also updated Photoshop CC 2014 without any issue.
Lightroom has installed only one link in programs and not a Folder and no link on Desktop. This link is directing to "C:\Program Files\Adobe\Adobe Lightroom\lightroom.exe".
I am using Windows 8.1 in 64bit. I have de-installed the new lightroom already and installed again. same result.
Does anyone have a tip what to do?
