Invalid section name in .INF file filename.
A section name in the .inf file might be incorrect. For example, Setup expects section names in an .inf file to be enclosed in square brackets. Or, the .inf file might be corrupted.
Click Retry to retry the operation. If you still get this message, click Exit Setup. Restore the .inf file from the installation disk (you will have to decompress the files). Then run the Setup operation again from the beginning. If you get this message again, contact your technical support group.
