We're running Windows Live Mail version 16.4.3528.331 on a Windows 8.1 system. At startup Windows Live Mail typically fails with code 0xc0000005, although we have also seen 0x40000015 in the Event Log. All we get is the initial 'blue' window at initialisation and then an error message saying the program has failed to start so we never see the normal WLM window. Since we cannot get into the WLM system it's a bit difficult to change any parameters or even check any information. I suspect the problem lies with the database rather than the program code but I can find no information on how we can check the database or even recreate it.

The faulting application path is C:\Program Files (x86)\Windows Live\Mail\wlmail.exe and the faulting module is identified as c:\Program Files (x86)\Windows Live\Mail\MSMAIL.DLL. We have uninstalled and downloaded the program code, hence my suspicion this is not where the problem lies.

Does anyone know of a way of validating the database or checking it? Or have any other suggestions as to what the problem might be.
