Alternative to Installer Badge

I have fairly successfully used the AIR installer badge to deploy my application for some years now [link removed by moderator] but have occasional problems with customers being unsuccessful with the installation insofar as the badge very quickly goes to say "Try Again" or the installer file is damaged.  I can usually have success if I get them to manually install AIR and then manually install our application (usually after they have turned off their anti-virus and firewall) but it is not a very good customer experience.  There can also be problems nowadays with people using new Mac computers as Apple do not pre-install Flash which means that the standard badge will not work.

Does anyone have any ideas for alternative one-click installation solutions?

Thanks
