I managed to get EE installed. Since then, I have purchased the Battle Pack and managed to get it installed. Don't ask me how I managed either -- I think persistence had as much to do with it as anything.
I've continued to buy all the expansions for this game, so you're at no risk of losing a customer at this point, but I must say that I've never experienced such difficulties getting expansions installed as I have with FOG. I routinely disable my firewall and antivirus programs before starting, and close out of all other programs, and still routinely have problems. I don't believe I've ever had an install take cleanly until after several tries.
On the Battle Pack, all the instructions indicated that I should patch up to 1.80 and then install it. The program itself set about to do this automatically (in fact, it didn't want to let me proceed until I had done it.) As usual, it would hang up and not install (nor would it unlock the data in the Battle Pack. After several days of trying to follow the directions, I apparently did something that upgraded me to version 1.81, after which the Battle Pack installed properly.
I'm not sure what you mean when you advise us to "unlock your expansions with the tool that comes with the game on the launcher". I have the CD version of the base game and each of the expansions. When I open the CD to view the files, I see nothing that suggests that there is an "unlock" capability that is independent of the setup launcher. Where would I find that?
I am also skittish about upgrading to the most recent version and then installing (although ultimately that seems to be what worked for the Battler Pack.) The reason: in the past, I found that upgrading to the most recent patch confuses earlier expansions. Evidently they are seeking an specific version of the game over which to install themselves and, when they find a later version, they don't want to proceed with the install. At one point, after initially installing the base game and then multiple expansions in any old order, I had to uninstall everything and reinstall in the exact order that the expansions were issued, without upgrading anything independently of what the next expansion itself wanted to do.
I've read some talk about a new generation of FOG. I hope that you will not pull the rug out from under us loyal customers by rendering all the existing expansions obsolete or incompatible with a new base game. It would be nice, however, if you could do something to make the installation less touchy than I (and apparently others) have experienced with the game in its current state.
Thanks, as always -- and please do let me know how to access the "unlock" function from the CD.
