Creative Cloud desktop app installs the new Lightroom CC but it wont launch - I've tried several times but nothing happens. (Windows 8.1) do I need to uninstall Lightroom 5.7 first?
Please check this link: https://forums.adobe.com/message/7460001#7460001
and if does not work
Please follow these steps:
Try to rename SLCacje to Slcache.old
C:\Program Files (x86)\Common Files\Adobe
SLStore to Slstore.old
and Right Click on the Adobe Lightroom icon and run as administrator.
Great, many thanks Sandeep that works
