How to Install
Repair Sys ProblemsFixing a corrupted or missing error is an easy process with a few steps. Open the zip-file you downloaded.Extract the .sys file to a location on your computer. We recommend you to unzip the file to the directory of the program that is requesting the file.
If that doesn't work, you will have to extract the file to your system directory.
By default, this is C:/WINNT/system32/drivers (Windows NT/2000).
or C:/Windows/system32/drivers (Windows XP, Vista, 7).
Make sure overwrite any existing files (but make a backup copy of the original file)
That should be it. Although not necessary you can reboot your computer as well.
