Lightroom 3 and 4 co-existence
I just installed the newest version of Lightroom 4 on the computer , where I have 3.6 already.
During the installation, no upgrade/fresh installation questions were set, it only asked me to upgrade the exisiting catalog, which I placed into separate directory under different name.
Is there any reason to keep both versions ?
Can I uninstall LR 3.6 manually now , without any risk ?
Should I unregister it , if available ?
Can I delete old catalog directory then, including catalog, LR settings and backups?
