WinXP Search Companion

Hi

I've found this problem w my just winxp re-installed laptop.
How do I fix this ??

Start Menu>Search>Files and Folders>
Error: "A file that is required to run Search Companion cannot be found. You
may need to run setup."

So I did this which did NOT work:
Run>regsvr32 %systemroot%\inf\srchasst.PNF
C:\WINDOWS\inf\srchasst.PNF is not an executable file and no registration
helper is registered for this file type.

cheers
Andrew
