Wes, you asked for an official explanation about how to get MM2 to work on W2K, so here it is. I took notes while I installed the latest update so I know all the steps are there.
Here goes: (Note that this solution is necessary because Modswapper does not work with W2K.) 

1)Unzip all the MM2 zip files to a unique folder. I use d:\CTP2_Senarios.
 
2) Copy all the files to their respective folders in the Activision folder. They are saved under the proper folder names when they are unzipped. I just put them under a different higher folder name.
 
3) Copy all of the following files out of the Activision folders and save them in a seperate directory. \\Activision\ctp2_data\English\Great_Library.txt,
\\Activision\ctp2_data\Default\Newsprite.txt,
\\Activision\ctp2_data\Default\Wondermovie.txt,
\\Activision\ctp2_data\Default\Victorymovie.txt, 
\\Activision\ctp2_data\Default\gamefile.txt. 

4) Once you have saved all the above files into a seperate directory, perhaps called "original", delete them from the game folders. 

5) Rename the following files as described;
\\Activision\ctp2_data\English\MM2_Great_Library.txt 	to \\Activision\ctp2_data\English\Great_Library.txt, \\Activision\ctp2_data\Default\MM2_Newsprite.txt 	to \\Activision\ctp2_data\Default\Newsprite.txt, \\Activision\ctp2_data\Default\MM2_Wondermovie.txt 	to \\Activision\ctp2_data\Default\Wondermovie.txt, \\Activision\ctp2_data\Default\MM2_Victorymovie.txt 	to \\Activision\ctp2_data\Default\Victorymovie.txt, 
\\Activision\ctp2_data\Default\MM2_gamefile.txt 	to \\Activision\ctp2_data\Default\Gamefile.txt 

6) Copy \\Activision\ctp2_data\English\Great_Library.txt to \\Activision\ctp2_data\Default\Great_Library.txt 

7) Open up \\Activision\ctp2_data\Default\Gamefile.txt in Notepad or some other text editor and make the following changes;
change MM2_Wondermovie.txt   to Wondermovie.txt,
change MM2_Victorymovie.txt  to Victorymovie.txt,
change MM2_Great_Library.txt to Great_Library.txt,
change MM2_Newsprite.txt     to Newsprite.txt. 

If you follow all these steps things should work fine. Once this is done, if for some inconcievable reason you want to go back to the original game, just copy the saved original files back into their original directories and everything should be back to the same old unchallenging CTP2 many of us have grown to loath and despise.
