I recently bought a new PC and uploaded lightroom CC, but before it used to open up at the last place I left it (including all the settings) but now it opens up in library and I have to open up all the panels amend the export data etc. I'm sure there must be a tick box somewhere but I just can't find it! can anyone help? thanks for your time
You moved your image files and LR Catalog file & Previews folder over to the new system, correct? LR converts the previous version (LR5?) catalog for use with LRCC and moves over the old Preferences file. It appears the Preferences file can become corrupted during this process and must be reset. Follow the procedure as outlined here and see if it corrects the issue:
I am guessing that when you copied the catalog and previews to the new computer, you forgot to copy the LR preferences file and probably forgot to copy your preset files as well.
