User getting Windows Application Error relating to referenced memory not readable

In general, this error indicates a probem with the application. All we know is that a memory location could not be read. What's a bit weird is the address of that location: It is at the very beginning on the address space and there is a good chance that this address is actually wrong, and the operating system is protecting this location from being read. There could be a number of reasons for that - here are a few that are more likely: Hardware problems (e.g. bits are flipping at random), virus or malware, or a simple bug in the application. I would start with a virus/malware scan.
