问题
I have .Net application developed with C#, using C++ library, running on 64-bit Windows 7 OS but in 32 bit mode. Everything was fine until recently I started migration of this application to 64-bit mode. During work on this I returned to my 32-bit original version and now it does not work. When launching it crashes after several seconds barely opening dialog box notifying something about uder-defined breakpoint and then completely disappears on its own. What interesting is that when I just rename the application's executable (e.g. App.exe to App_.exe) it is working fine. It is really weird situation as I do not changed anything but name of the executable. I have a feeling there is some registration somewhere in Framework which causes a problem.I checked Event Logger and say this:
Faulting application name: MyApp.exe, version: 1.0.0.0, time stamp: 0x5310c171 Faulting module name: ntdll.dll, version: 6.1.7601.18229, time stamp: 0x51fb1072 Exception code: 0x80000003 Fault offset: 0x0001000c Faulting process id: 0x%9 Faulting application start time: 0x%10 Faulting application path: %11 Faulting module path: %12
Please help me with this.

I know it's been a while since your post, but I just ran into the same problem and found a solution :
I removed the key corresponding to the app in the registry :
\HK_LOCAL_MACIHNE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\[App.exe]
Hope it helps
