Microsot SQL Server 2000 install error on SBS2003

I have an issue that a million other people have had , but the posted KB article doesn't help

After entering the CD key for SQL server 2000 , i get "unable to validate cd key" error

There are a number of KB articles that tell me to add a key to the registry -:
SafeDLLSearchMode  -- to -- HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager

another suggested a similar dword --: SafeDllSearchModeTemp --to--  the same location

I have tried both in current control set and all the other control sets in a vain attempt to succeed

the error still comes up , im lost i cant find anything else that would help online...


 i checked the cd key its fine i also tried a few other keys and they give the same result


PLs Help
