10. If you do not receive the error message when you run the Add New Hardware wizard, the damaged .inf file is one of the files you moved in step 6. To identify the damaged .inf file, move the .inf files back into the Inf folder one at a time (noting the name of the .inf file you are moving), and then repeat steps 7-8. Repeat this process until you receive the error message again. When you receive the error message again, the last .inf file you moved is the damaged .inf file. To determine where this file originated, double-click the file and note any manufacturer, version, or date information that may indicate the origin of the file. After you determine the origin of the file, delete the file, and then reinstall it from the original installation disks or CD-ROM.
