I've installed LightroomCC via cloud, but it does not run
Windows 7 latest upgrades done.
The solution for most folks is to open their Creative Cloud App, click the gear, click Preferences, Sign Out and then Sign back in.
If that doesn't get it,
Try Solution 3 here: Lightroom doesn't launch or returns "Develop module is disabled" error after 5.5 update
Seems to have worked after all options tried - thanks
