What’s Behind the Error Code 0xc0000005
Like other BSOD problems, there is a staggering list of causes of the application was unable to start correctly (0xc0000005). Since putting down every possible cause of it and trying out respective possible solutions would be time-consuming, this article will only show the three most common causes along with several working solutions.
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

Windows Installation Error
This particular error occurs when the computer is in the process of installing an operating system. Possible causes are incompatibility between the operating system and the partition, defective RAM, or corrupted hard drive.
