I am trying to re-install RCV4 on a new disk. I have obtained a new registration code but when I try to apply it after entering it I get: Runtime error 75. RadarContact.rcv4module.write_keyboard.It works perfectly on the original system.Help please.

Be sure you are logged in as an admin. Start RC with Run As Amin properties or better set up a shortcut to it with the shortcut property set to Run As Admin. This applies to VISTA and Win 7 users.Error 75 means RC can't find or access a file. RC needs admin privileges to communicate with your FS folder and its add-ons.After you succeed in registering be sure you update FSUIPC and Makerwys.exe from the links at the forum top.FYI, keyboard.ini resides in the RC folder.Also check the security topic Error 75 thread pinned at the forum top.
