Adobe AIR - Inconsistencies in detecting whether Adobe AIR runtime is installed

I am having issues detecting whether Adobe AIR is installed using the following process: http://livedocs.adobe.com/flex/3/html/help.html?content=distributing_apps_3.html

Having installed Adobe AIR 1.5, we are at times getting a value of not installed from the getStatus() function of the air.swf located at http://air开发者_StackOverflow社区download.adobe.com/air/browserapi/air.swf

Has anyone else faced this issue before? If so, does anyone have any steps to resolve it?

After doing some more research on the issue, I have found other users encountering the same issue we are:

In the second thread, it says:

“My issue seems to be specifically related to the use of "Silent Install". My client has a distribution license for the AIR runtime and is bundling the AIR installer with their installer. When Silent Install is used to install the AIR Runtime, Adobe's air.swf reports that the runtime is not installed. This happens until the user initiates an air app, at which point air.swf is able to detect the runtime installation.””

This seems to suggest there is a bug with the Silent Installer or with the air.swf getStatus function. I tried the steps above and was able to recreate and resolve the issue. Does anyone else know of a different workaround?
