Google Translate says:

Failing application name: xxx.exe, Version: 1.0.0.0, time stamp: 0x4db446eb
Failing module name: mscorwks.dll, version: 2.0.50727.4927, time stamp: 0x4a275a68
Exception Code: 0xc0000005
Fault offset: 0x002063db
Process ID that has failed: 0x% 9
Start time of an application that has failed: 0x% 10
Faulty application path:% 11
Module path that has failed:% 12
Report ID:% 13

0xc0000005 is an access violation exception, something in the code is trying to access memory that doesn't belong to it (or doesn't exist).

Since mscorwks.dll is part of .Net, (I think) and will have been thoroughly tested, both by Microsoft and their "field testers" (i.e., users), it's more likely to be a problem in your xxx.exe application.

You might want to try running it under a debugger so you can more easily figure out exactly what the problem is. Debugging is usually more revealing than post-mortem analysis, especially for a generic problem like this that could have a thousand different causes.
