The problem may be with old versions of system files conflicting with new versions of the same system files.

On Windows-based systems, particularly with Windows 95 and 98, software applications that you install may install an updated system file.

But instead of replacing an old system file, it often puts the new system file in its own application folder.

The problem that occurs is that other applications that use this system file will load the old version from your System folder.

Then you run the new application that uses the same system file, but uses the newer version instead.

The problem is that only one copy of the system file can be in memory at a time, so the new program will try to do something that does not exist in the old system file, thus causing the "Illegal Operation".

RJ System File Checker scans your system for duplicate system files and eliminates the old versions.

You have the option of having RJ System File Checker automatically do the work for you and reporting on what it did, or you can have it present a listing of all duplicate system files and version information to determine the best course of action.

RJ System File Checker will also back up all system files it removes, so that you can easily restore a system file that is needed.We at RJ Solutions recommend using RJ System File Checker with care, as carelessly removing system files can make your Windows operating system completely inoperable--even possibly preventing Windows from booting.

The automated facility does function well, but you should review what actions were taken when the process completes.RJ System File Checker is an excellent tool and has recevied high ratings from several shareware sites, including four stars at Yippee.net.
