Hello,
Am not able to install any updates for lightroom 4 on my Windows 7 system. I originally installed the program from a CD, and now can't update the program. I chose the administrative privileges for the update. The error I receive is 'A problem occurred while extracting some files. Check available space on your computer and the write privileges on the destination folder'. The update file is Lightroom_4_LSII_win_4_3.exe.
I am using the folder that was made during the original installation. Thanks for your help. Don
