have read through the forms, manually downloaded the 6.4 update. Get error code U44M1P7 at 99%. The other option is do uninstall program and reinstall.
No explanation on if you loose pictures or not.
How does one get the latest update to Lightroom....
Can not find Option one - Library
Option 2 does not work
Option 3 - don't want to lose pictures
Simply no real help. Hard to find the section to even PAY for help. This is beyond madding. Adobe, fix your programs. You CSI scores should be the lowest of low by reading all the people who can not find answer to their issues. You make people spend hours trying to fix your programs.
You do not lose pictures if you remove and reinstall LR.
Your catalog - where all your work is stored - will not be removed and you can open it again after you reinstalled LR.
Pictures are not stored in LR anyway - LR only keeps a pointer to your original pictures.
