What is the exception unknown software exception 0e06d7363 occurred in the application at location 087c81eb33?

This is a fault caused by the software that you were running at the time. If you started a program just before getting this error, that would be the suspect. If not it could be ANY program that was running at the time. It could also be caused by a driver conflict with some software.

To fix this kind of error, because we have very little info to go on, we need to use a Microsoft tool to read the dump file that Windows created for this problem. The Dump Check utility which is included with the debugging tools for XP will do that for you.

The link to the Debugging tools and a full explanation on how to use them can be found at the Microsoft site. They are listed under KB315263.

If you surf to support.Microsoft.com and do a search for KB315263 you will get to the page that explains how to use the Dump Check utility as well as having the links for the free tool.
