In my case (Windows XP) helped to check a registry (by using regedit), there should be your serial number in keys:
HKEY_LOCAL_MACHINE/Software/ElectronicArts/EA Games/Command and Conquer Generals/ergc
and
HKEY_LOCAL_MACHINE/Software/Electronic Arts/EA Games/Generals/ergc - this one was missing
after clicking on ergc in the treelist you should see item Default(Name column) and value (Data column) is your serial number. I created the second one and since then it works- no more "Registr is corrupt" messages!
This fixes Zero Hour but will not do anything for regular Generals. Is there ANYTHING that can be done?
