Am I correct that you are: Writing and installing a keyboard hook? Trigger an assertion in your code when you start Internet Explorer? What assertion do you get? What is the code that gives the assertion? Since you are getting an assertion, the place to look is at that assertion. Ask yourself: What is the expected condition that was violated? Can I trace this back from the occurence of the assertion to the origin of the problem?

Please do not read this signature.

Reach out to the source file and line number specified in the assertion, and see what condition is failing.

It looks like it's actually the fwrite() line that's failing. You can tell from the assertion that your fopen() call failed. That means you don't have anything to write to but your still trying. That's why you get the assertion. Handle the case of when fopen() fails.
