for last 3 days i m trying to reinstall Visual studio 6 in my PC, from my visual studio cd. but it showed an error message and that is

"unable to register C:\Program Files\Tools\VS-Ent98\Vanalyzr\VAIEC.DLL"
i fixed this problem with the command
regsvr32.exe "C:\Program Files\Tools\VS-Ent98\Vanalyzr\VAIEC.exe"

and the dll file was successfully registered. but after that when i was trying to reinstall visual studio 6 it shows another problem. that is

"Setup is unable to create a DCOM user account in order to register C:\Program Files\Tools\VS-Ent98\Vanalyzr\VAIEC.exe"

i cant understand what is problem with it.
