Deven,
I've never disabled a system yet with regedit

That said, then you export the following path as a .reg file:
HKEY_CURRENT_USER\Software\Camera Bits, Inc.\Photo Mechanic
Then you need to edit the .reg file with a text editor and remove anything that has a path in it, like the CachePath entry unless the path already exists on your other system.
Then you take the file over to your other system and import it back into the same location using RegEdit.

Other settings (snapshots) are just simple files and can be copied from one system to the next. You can find the snapshots by using PM directly. Just hold down the shift key while you choose a snapshot from the popup menu. Windows Explorer will come forward, displaying the file. All of the snapshots are saved in feature-specific folders and the folders are all together in the same parent folder. Just copy the folders full of snapshots to the other system into the same location.
