Error message when downloading adobe air app.

I have according to the installation program successfully installed adobe air. I am now trying to download an adobe air app from Jacqui Lawson and keep getting the following message.

"Sorry an error has occurred. The application could not be installed. Try installing it again. If the problem persists, contact the application author."

I have read other comments regarding this matter and tried everything suggested so far. I am still having the same issue.

I am running windows vista 32 bit. All firewall and anti virus are off, UAC is enabled, I have uninstalled and reinstalled the program and I have tried using a different browser. Can anyone suggest anything else to try.
