My App crashes in Windows 7 and Windows Vista
I have developed an application using Visual Studio 2005. The application runs fine on Windows XP but crashes on Windows 7 and Windows Vista.
I checked the event logs and saw this:

Is compiling the project on Windows 7 and Windows Vista a possible solution? I could try but if its not a solution I would not spend time setting up Vista and W7 development machine.
Re: My App crashes in Windows 7 and Windows Vista
That event report tells you (or us) nothing about why your program crashed.
No, you shouldn't have to re-compile on Vista or 7 to get it to work properly.
It's a bug in your application that needs to be fixed. You could try using the MSVC debugger from inside Vista or 7 to see whats going on at the time of the crash.
If it's a small program, you could also try posting the source.

To add to what ChrisF stated:
If you're going to support multiple OS'es with your program, it is imperative that you're prepared to debug your program on all of your supported platforms.
Secondly, just because it seems to run fine on XP doesn't mean the program is really OK. The other operating system's could have exposed a bug that isn't exposed when run on XP.

Re: My App crashes in Windows 7 and Windows Vista
I dealt with a similar situation before. In case your app doesn't provide any internal output of debugging information, and if you cannot run it through a debugger in Windows Vista/7 you can use the following approach I described in a previous thread:

(None that the post above is taken out of a context of the aforementioned thread.)
Re: My App crashes in Windows 7 and Windows Vista
You may also want to try Microsoft's Application Verifier. It's not the best way to debug, but, it can spot things that are missed by other means.
Re: My App crashes in Windows 7 and Windows Vista
ahmd, you're post is such a huge help. Was able to acquire the .mdmp and .hdmp along with other files.
Doing exactly as you mentioned, I was able to trace the crash at free.c in the following lines of codes
Code:
retval = HeapFree(_crtheap, 0, pBlock);
if (retval == 0)
Could the reason be because of a code that calls free() on a memory that wasn't really allocated? I am to trace the code tomorrow.. this post is some sort of update on this topic :)
ahmd, thank you very much!

You need to see what your code called to get to that point. You should inspect the call stack, not just where the crash is reported. The call stack will show you the series of functions that ultimately called the one that you are showing.

It means you more than likely are mismanaging pointers and dynamically allocated memory. That could have occurred anywhere in your program where you're doing this.
So it looks like the issue, if this info you're giving us is correct, is exactly as I stated -- your program always had a lurking bug, it just wasn't exposed when running under XP.
A C++ program need not crash when you make a mistake -- the behavior of a program that has memory related bugs is undefined. The program could work, crash, work sometimes and crash other times, work on one machine and crash on another, etc.

Re: My App crashes in Windows 7 and Windows Vista
Paul is absolutely correct, the fact that your program didn't crash under Windows XP simply means that XP manages memory differently but the bug was always there. I've seen this a million times. So look through the call stack to trace it back to a function/method in your own code that causes the crash. Although judging by your previous post, most certainly you have some sort of a buffer overrun, or use a pointed to a memory block that was previously released. There are a million of possibilities here without seeing the code... I agree with one though -- it is quite a b**ch to deal with if it wasn't caught immediately during development. Good luck.
