Air.swf getApplicationVersion() not calling back

Question

I am trying to use air.swf from
http://airdownload.adobe.com/air/browserapi
per the Adobe documentation to detect if an air application is
already installed. I'm using getApplicationVersion but the callback
function is never called. launchApplication() and
installApplication() work fine.
The code looks like this:
_air.getApplicationVersion(appID, pubID,
versionDetectCallback);
function versionDetectCallback(version:String):void { do
stuff }
VersionDetectCallback() is never called. I de-compiled the
air.swf and ran the code directly to try and figure out what's
failing. But I get the same result. I can see the timer on the
LocalConnection endpoint timing out after 5 seconds. I just can't
figure out why the appinstaller is not calling back. The actual
call (taken from the decompiled swf) looks like this:
airappinstaller = new ProductManager("airappinstaller");
var launchArgs:Array;
launchArgs = ["-isinstalled", appID, pubID, "adobe.com" + ":"
+ lcName, "onApplicationVersion"];
airappinstaller.launch(launchArgs.join(" "));
where onApplicationVersion is the endpoint callback function
and lcName is the LocalConnection name.
It doesn't matter if I make the call from the Loader Init
event or in a button click the callback function is never called. I
am using Flash CS3.

Hi Lisa,
I am on windows yes,  and I seem to have got it working.  I found this problem to be very perculiar as there were many things my badge didnt like - such as a case statement instead of a load if if's.   anyway my solution is below,  although I must say, that now nothing happens if the user doesnt have air installed!  If they have Air installed but not my application, it will install my app but the need air installed first and that is not ideal!
Maybe implementing your timer solution may help this?  Thanks for taking an interest!
