ASMS ERROR MESSAGE

Hi, I am installing XP pro and when it gets to the installation part I get this which happened to me last year.......

The file 'Asms' on Windows XP Professional CD-ROM is needed. Type the path where the file is located, and then click OK.

I did a google search and did what I found but it don't work. Using the regedit via command session thing. Any suggestions? Thanks and have a GRATE DAY!
