Access Violation

This error occurs when a program launched by users fails to a location that is not granted to it. Virtually all windows applications could bring about this error when there are problems such as registry issues, corrupted drivers, and faulty RAM.

The Application Was Unable to Start

You may be confronted with this error when trying to launch some software, such as VLC and Chrome browser. Reinstalling it will not work in most cases because the problem often results from unsigned, invalid, or incomplete DLL files that are indispensable for launching software.

Windows Installation Error
