Multiple non-conflicting mods

[Marshall]

Progress update:
Attached are some images of how the interface is shaping up.
I will probably be including a 'check for updates' facility - as you can see from the interface design.

How will the update facility work?
1. Author specifies a url to an ini file. Program downloads and reads this ini file.
2. The ini file contains the "Previous Version", the "Latest Version", the "Update Download URL" and the "Full Download URL".
3. If the user already has the "Previous Version" or later, then the "Update Download" will be downloaded and executed. If the user has an earlier version, or the "Update Download URL" is not specified, then the "Full Download" will be downloaded and executed.

On clicking 'Tools > Check For Updates', the program will check for updates to all installed mods and display them in the grid. The user can then select an update to download or cancel and return to the main screen.


Questions:
In order for people to detect the presence of the program, I am thinking about including a single registry entry to identify the program's location. This entry will be maintained by the program - every time the program loads it will update the registry with the location of the program. This way, the user can wipe their registry without breaking the program.

This also begs the question of whether or not mods [subfolders] should be installed to the program's directory, or the Red Alert 2 directory?
