Using aim:goim -> redirect user to download aim client ?

Hello.

I'm new to communicating with AIM. I'm using a simple "aim:goim?screenname=SCREENNAME" for a web button. It works quite well but of course, if the user's browser can't find an AIM client, it just displays a cryptic error message in the browser window..

My question, is there any way - perhaps with javascript - that if the user doesn't have aim installed, instead of the text error message it sends them to the AIM client download page? Skype buttons work this way. I was just wondering if there is something similar with an AIM button.

Thanks in advance!!

That is not possible, ie., if none of the AIM software is installed. To do
what you suggest, we would have to install something to handle the aim URL.
There is no guarenteed way for a web page to check if AIM is installed, but
you could look for the AIM install directory in Program Files\AIM6 or
Program Files\AIM on your web page and then message the user yourself to go
to the AIM install page. AIM may change the install directory at any time,
so you may need to maintain this code if you decide to do this.
