Cannot install Pipe Creek to D drive

[cgoddard]

Had the Gettysburg game for a while installed on my D drive fine.

The 1.5 patch would only install onto my C drive (which is a small SSD). I was able to cut and paste into my D drive and the game seems to be patched.

Now installing Pipe Creek and have hit the same issue but copying the install accross does not show when starting game.

Have sent a support ticket but wondered if anyone else has had this issue?

UPDATE

In reading about a similar issue I got enough info to edit my registry as it was somehow listing Gettysburg on the C drive when it is in fact on the D drive. Once I did that then it installed coreectly to the D drive and now shows in game menus
