The 2 methods described are the "right" way to move the directory, both of those guys are Nebula geniuses. But I successfully moved mine when I was still very new to Nebula. It is very simple but more laborious. Back-up all of your Neb stuff first. Now, just move it. Cut and paste the entire nebulatemprepository to the new location. Now the fun part. Completely uninstall your Nebula installation, but leaving the temprepository where you put it. Run ccleaner and it's registry cleaner. Don't use some intensive registry cleaning program (ever, as far as I'm concerned!), they can wreak havoc on your system. Just something light like ccleaner. Next, reinstall your Nebula program, like for the first time, and specify where your nebulatemprepository is. After you get that done right, run your license file, just to make sure it is all working. For extra measures, delete the contents of the temp folder in your temprepository, and also delete the "~scanboot" (but NOT the "Rom" file!) in the "Setups" foler in the repository. This will empty your program cache, so when you start Nebula the first time, it may take a while to load. Hopefully, you've backed things up like I suggested, but it should be fine. I have since done this another time very successfully. If you are comfortable editing the xml file, obviously that is MUCH easier. But when I was newer and NEEDED to move my libraries, this was a method that I did understand, and it works. Good luck!
Thanks for all the help. I moved 'nebulatemprepository' onto a new drive partition and simply changed the drive letter to the new one in the xml files and everything works flawlessly. Couldn't have been easier.
My only concern now is if I decide to uninstall Nebula Pro. Will I need to move the whole 'nebulatemprepository' back to the C:\ drive or just 'uninstal3.exe' and 'UninstallCudaBridge.exe' files?
I'm not intending to uninstall Neb Pro but just in case.
