Thanks for your reply. Sorry, the software doing nothing after I clicked it.
it will ask me to active the file after I sign out, but nothing happen after I signed in...
I tried to hold on Ctrl and click, it will ask me to select catalog, nothing happen after I select or create a catalog.
Don't know where to look into to fix it...
Please open Device manager/Activity monitor and check whether Lightroom shows up or not when you launch it.
didn't work for run as administrator, or change GPU
but repair MSVCR110.dll does fix the problem!! thanks a lot!!!
