The INF File Syntax Checker, or ChkINF, is a Perl script that checks the structure and syntax of Microsoft® Windows® 2000 and Windows XP driver .inf files. Results are presented in HTML format, and include a list of the errors and warnings detected in each .inf file, with each error and warning shown next to the errant .inf file entry. Note that ChkINF does not support Windows 98 or Windows Me .inf files.
The ChkINF tool includes support for all .inf sections and directives that apply to all classes of devices.

In addition, ChkINF has device-class-specific support for many device classes. It also can check .inf files used for installing many classes of file system drivers. For a complete list of these classes, see the chkinf.htm file that is located in the Tools\chkinf subdirectory of the DDK.

ChkINF has not been extensively tested. Review your results carefully.

Попробовал установить - все равно выдает эту ошибку. Щас пытаюсь изменять внутренности INF файла.
