Gentlemen, thanks for your replies. After I posted here I checked out TW Center and saw that I wasn't the only one with that dilemma. I ended up finding enough other things to move out of my C drive to give myself the required minimum hard drive space for the M2TW Gold installation. The process then moved along to the point where I was allowed, finally, to redirect the installation to the drive that had room for it. After that I started the game and played a couple of custom battles and for now all appears to be well. One little detail, though, - I didn't post at TW Center, although I read everything that other folks posted. In fact, I have yet to post at those forums. Meanwhile, I wonder what we who shell out the money for these games can do to make these companies care about the software they write and its likely effect on potential and actual users. After all, they don't give these games away. Fair is fair, or so I've been led to believe.
