Ah, where to start from...say with gecko.
Gecko is needed by some windows installers. It says that is better to install the distro provided package. True if you're installing the game from your main wine.
But since Playonlinux uses separated wine instances (and often different versions) in separated enclosed environments, installing from package manager will do no good.
In other words Plyonlinux will be unable to use it because it doesn't see the main wine installation.
So is better to let that "grey window" on and finish the download. And yes, you will have to do it (almost) every-time you install a game.
Sometimes it just hangs there (don't ask me why...) but eventually (and hopefully) will finish the download and proceed with the installer.
Now, even when something is going wrong (you kill the window or doesn't get to finish the download) is not the end of the world. The installer will continue but will have some elements missing (some images or some text). Even in that state is possible to proceed.
About the installer asking for the CD's...well heck yeah
Something like Dedanna says: they provide the means, you provide the media

What next...AGE III.
First of all, when clicking on AOE in Playonlinux's list it says there that...wait...
Game won't run with original age3.exe.
What exactly means that, I'm not sure. I suppose is their way to suggest that you need a crack to run it, even if the disc is original.
Wine/Playonlinux doesn't deal with copy protection (for legal reasons) so is unable to get past that if the game is protected. Is a legally gray area here so I won't get any further.(farther?...I'm always confusing these two).
A word about desktop icons.
When you install a game with Playonlinux the game installer will put (most of the time) an icon (or even two) on the desktop.
Don't use them.If you click on them, the game will start (or try to ) using the main Wine,
and Not the customized wine from within Playonlinux.
At the end of the installation when Playonlinux is asking about creating icons, choose only to put icons on Playonlinux menu and start the game from there.
If you want to see error messages (if any) go to your home folder where is the hidden folder
.Playonlinux.
Inside the
.Playonlinux folder go to /configurations/installed folder, where you'll find the shells used to start the game.
Edit the shell first by commenting the line:
So, will look like this"
This will enable all the error messages to be shown.
Start the shell from console this time, not from Playonlinux's menu.
Aaaaand I'm stuck...got no other ideas for the moment.
