I'm currently working on a batch file that leads you through the whole installation process of Morroblivion, unzipping files and starting all the necessary programs. Just wanted to check if anyone is interested in this?
This is what i've got so far:
You place all the required installation files, such as Support Files etc, in a directory and the batch files does the rest in the correct order and finally launches the Morrowind_ob.esm Master File Installer.

FAQ
I don't mean to rain on your parade, and it looks like you've put a lot of time into this, but please don't do this - please read the FAQ regarding why there is no 1-click installer.
If you just want to make a program that copies all of the miscellaneous files from one directory to the oblivion directory, and backs up the oblivion directory, why wouldn't you use Wrye Bash or OBMM, which do the exact same thing but much more efficiently?
