OS compatibility issues.

I developed a program for a video game (before you ask upon looking at the code, yes, it is an adult game) that I own that makes it a lot easier for people to use the video game's unpacking tool for making and installing mods. Unfortunately, I've already had two people report issues with the program on XP and 7. While the XP issue seems to be unsolvable until I download VS 2012 (I programmed this in VS 2010), I can't seem to find a solution to the Windows 7 compatibility issue, as all of my research would point to either re-installing the software which doesn't seem to apply here since there is no install to my program (it's a lone .exe), or putting exception handling in the code, but I would have no idea where to put it if the program is crashing on startup. Therefore I am asking if the Windows 7 compatibility issue can be found somewhere in the code itself, or if it is due to some other issue.

The program is designed to delete and rewrite a configuration file for the game's unpacking program, and then upon rewriting the configuration file, it runs the external unpacking program.

My OS is Windows Vista Home Premium 64-bit.

Here is the whole program:

Code:

There are many things that can go wrong, one such thing is a change in permissions to various folders where files are stored. Does the user enter a path to the file or is this auto-generated? It could be something as simple as the app not having permissions to write to the file location. It's hard to tell from the code, but you may need to check for errors and add some logging to the app.

No, the path isn't auto-generated, as the user needs to tell the program where their game is installed, only the little end bits are generated for the specific areas in the game's main folder. While permission issues could be a problem, the users were reporting that my program would crash on start up, and not when the program's file writing is executed (which is via a button press), so the current issues that users are having can't be related to file permissions.

I didn't expect to guess on the first try, so here's what you need to do:

Well, I'll put some try and catch statements around what's inside the form1_load event, since it's crashing on startup and just have it catch all exceptions for now just to see if that is where it's actually crashing.

Is there a way to log stuff without using filestreams and stuff like that, as if it is crashing on startup, I highly doubt it will write anything to a text file if I code in a filestream for writing logging text to a text file.
