Can I delete everything nebula on my computer except the programs and vectors for the libraries I have bought. Then download the newest version and reauthorize on the same computer with out troubles? at this point I have so many copies of version upgrades that I don't know what is going on. i just downloaded the newest version and i am not getting things working, due to my own ignorance of coarse.
Yes, you can do it. OSX framework or DLLs Windows files will be in the same place. Remember if you use Nebula3 Server you should install first Pro version. You should not register online you product again, but you must to install you personal key.
NOTE: double check path in Windows, they are not fixed like in OSX.
