An installer for GAE 0.2.12a was just finished today!

However, you know the drill. At its filesize (70MB!) it will need a little time so I can get the access to upload it. Honestly, I wish my school had WiFi. It used to, but some idiot removed it and converted all the school computers to being wired. Ugh. Stupid, inconvenient, and messy!
To install it the hard way, download the zip provided by silnarm that has the windows binary and the lua dll, then download the new GAE data files and put both of these in the glest directory. Now take all your scenarios and place them in the gae/scenarios folder. To fix language errors, open the gae/data/language folder and copy en.lng, naming it english.lng. I can't remember, but it may be neccessary to add 'english=English' to the language list txt file there.
Hope that helps. If not, just wait for the installer. It installs EVERYTHING needed, so that GAE can work standalone. It also has the option to install FPM (and you may as well, since that is included with the installer). I hoped to add downloads for some of the major mods with it too, but it only works with zip files, and no one uses zip archiving for their mods anymore...
