The Windows\inf folder is a hidden folder. You can adjust your Explorer Folder Options (View tab) to Show hidden files and folders. You can also click Start, Run and enter %SystemRoot%\inf to open directly to the inf folder.
Error: "A file that is required to run Search Companion cannot be found. You may need to run setup".
The file that is missing, or corrupt, is one of two. BAR.XSL or BALLOON.XSL (and/or other files in the same folder), depending on your search preferences. These files are both normally located in the Windows\srchasst\mui\0409 folder on your hard drive. These files may be locally cached in the Temporary Internet Files, so this may explain why some users have this problem "intermittently". Re-installing srchasst.inf works here as well.
