Even though I have Tactics running fantastically (thanks GOG!) for whatever reason, it's not appearing in my Vista Games tab with the box art and such.
Is anyone else having this issue? And if so, how did you go about fixing it?

You can right click on the games option in the start menu and open it, you should be able to just drag & drop a shortcut in there
As long as you have the download info from the net option on, it should find & locate the box art, mine managed to find the box art for Sid Meiers Alpha Centauri which is just shy of a decade old. Failing that there should be a box art image in the install folder & you could change the icon manually

You'd think so, right? But that doesn't seem to be the case. Moving a shortcut there, just running the game and so forth - none of it works.
I can't seem to get the damn thing to stick in the Vista Games tab.

I know it's not a huge deal but I'd still like to figure it ou.

I was hoping it wouldn't come to using the VGEE but here we are =) Thanks for the help!

Only glad to be of assistance, and that program actually looks rather nifty? :-)
