How to solve this error that is shown on Windbg?

Question

I've loaded a .exe and it gave this error:

Microsoft (R) Windows Debugger Version 6.12.0002.633 X86
Copyright (c) Microsoft Corporation. All rights reserved.

CommandLine: "C:\Users\Public\SoundLog\Code\Código Python\SoundLog\dist\SoundLog.exe"
Symbol search path is: *** Invalid ***
****************************************************************************
* Symbol loading may be unreliable without a symbol search path.           *
* Use .symfix to have the debugger choose a symbol path.                   *
* After setting your symbol path, use .reload to refresh symbol locations. *

Then I pressed F5 and while executing the program gave me this error (this one is what I need to solve):

Can anyone tell me what is this and how can I solve it?

Answer 1

Your first issue is that you do not have a symbol path set. You can run ".symfix", as suggested in the message, to automatically select a symbol path using Microsoft's public symbol server. The second is an unhandled exception. You need to get proper symbols first, and then run "k" to get a stack trace that should give you more insight into what is happening.

Answer 2

You need to provide the path of the debug symbols. This can be done via the .sympath command.

.sympath c:\debugsymbols;srv*c:\debugmsft*http://msdl.microsoft.com/download/symbols
