I recently switched from Windows 98 to Windows XP. All is great so far except I cannot get my fax machine to operate. When I go into the configuring components section a box comes up that says. "The file fxsapi.dll on Windows XP Professional CD-Rom is needed". All-in-all there are about 29 files with this message. A friend @ work said it sounds like the files are not expanded. Any help would be wonderful. Thanks.
