If you happen to install, and play with mods for TC2M, or other games then I would suggest that you download, and install this great Generic Mod Enabler (JSGME).
For Most of my games I have which I have mods for I use this JSGME mod enabler. For instance, I have several Mods for TC2M, and for me to say install CMP3.0, and Horse & Musket I would have 3 copies of the game on my system to accommodate the mods, but with the Mod enabler, I no longer have to do that, one copy will work fine with this mode enabler. So, if I wish to play TC2M with CMP3.0 I just use the mod enabler to activate the mod, and if I wish to play the Horse, and Musket mod, I use the Mod enabler to disable the CMP3.0 mod, and enable the H&M mod etc, etc.
Those who know of this great util swear by it. So if you are interested, you can download it from the link below (latest version).
