No Crashdumps/Minidumps are saved

I have added an registry-key

SOFTWARE\Microsoft\Windows\Windows Error Reporting\LocalDumps\MyApp.exe

with the values

DumpCount 0x2
DumpType 0x1

to let Windows create a Minidump in case MyApp.exe crashes. The value for the path is not set in order to let Windows use the default storage location. Unfortuntately now after my application crashes, no dump is written to C:/Windows/Minidump (I added a memory access to 0x00000000 to the application in order to force a crash and to test writing of Minidumps).

Any idea what could be missing here?

Thanks!

Create/Write a DWORD(32-bit) value named "Disabled" under the key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Windows Error Reporting, and set it to 0 to turn on the WER or set to 1 to turn off.

If the value for the DumpFolder is not set, the Default value is %LOCALAPPDATA%\CrashDumps(According to Collecting User-Mode Dumps). Like:

And the "Report.wer" file is located at C:\ProgramData\Microsoft\Windows\WER\ReportArchive
