MS Office Program Start-Up Errors

I recently needed to re-Install my Office Professional 2000 on to my computer although the programs suite seems to work OK each time I start any of the programs Word, Excel etc... I receive this error [Compile error in hidden module: AutoExec] When I try to correct the problem by re-inserting the CD the program either can't find what it is looking for or can not copy, Can anyone advise as to what might be going on here?
Thanks,

Ron
