Understood. I'll keep my eyes open. BTW, if you have anything else to add on stuff that I should delete/create, PLEASE don't hesitate to update. Everything that I can use would be great.
Update: Have installed RA3 beta on test comp. Have used fake GAPP serial to get past initial installation request. Should I delete the SecuROM stuff now, or after I've opened the registry keys and updated them?
OK. Current steps I've taken:
Downloaded Lava's files directly on to flash drive, did not open on main system.
Deleted copy from temporary files in Documents and settings.
Disconnected test computer from printer and network (printer has fax line, doubt it could be used, but, meh. Won't hurt.)
Moved copy of RA3 Beta to Flash drive.
Double-checked for left behind copies of reg. files
Moved to test computer
Opened RA3 files and installed the files on I.
Used the code GAPP-9SHC-ALTK-TQVV-DYGR to bypass the first code request for the installation.
Copy of beta reg. files remains unopened on my flash.
Edit: Opened RA3 (without connection to internet and NOT having used the updated reg. keys)
Error comes back, Game cannot start, must be connected to the internet.
Where to now?

Edit: By changelog, do you mean a list of items that I do, or a list of things that I change in the files?
