Ok, When i try to run the Editor using Visual 2015 it display a lot or error messages says “Access violation reading location” each message with different adress in memory the first was 0x00007FFDF5C2E04D (OvlDynExt.dll) than 0x00007FFDF5C2E04D (OvlDynExt.dll) , 0x00007FFDF5C2E04D (OvlDynExt.dll), 0x00007FFDF5C2E04D (OvlDynExt.dll) …etc
This is the full first message:
Exception thrown at 0x00007FFDF590E04D (OvlDynExt.dll) in UE4Editor.exe: 0xC0000005: Access violation reading location 0x00007FFDF55CB430.
If there is a handler for this exception, the program may be safely continued.
