wntdll.pdb not loaded - Can't see the exception

Question

Sometimes when I quit my application (SaviHOST running a DLL that I'm making) I show this screen:

Unfortunately I don't know where the error happens, because it just load that screen, not the line where the exception is made.

How can I fix this? What wntdll.pdb have to do with this? Thanks

Answer 1

1. Connect to Internet.
2. Enable Microsoft Symbol Servers in Symbol path settings.

3. Close VS (I used VS 2015)
4. Restart and Debug With Native. All symbols will be loaded from MS Servers.
