Have had Lightoom 4 with no problems - upgraded to lightroom 6 which worked for a while but now won't launch. Have changed the cache and store files to cacheold and storeold as per adobe troubleshooting which also worked for a while but now it won't launch again and I have both the cacheold/storeold and cache/store files. Any suggestions?
Try launching directly from the app
On windows navigate to:
C:\Program Files\Adobe\Adobe Lightroom
Select lightroom (the application) and right-click and choose Send to Desktop.
On Mac OSX launch Finder and go to:
Macintosh HD >> Applications >> Adobe Lightroom >> Adobe Lightroom.app
After launching the app right-click (control-click) on the dock icon and choose:
Options >> Keep in Dock
Hi 99jon - tried that but still had to force quit. Thanks for the suggestions though
