We have encountered a problem with our AIR2 app (compiled to a native.exe installer) and openWithDefaultApplication on XP.
We are using it to open the downloaded update.exe for our application. Sometimes on windows XP the call to openWithDefaultApplication simply does nothing. This has occurred both on machines without firewalls/antivirus running and those with one or both running.
Any ideas what the problem is? It only fails sometimes not every time, but it failing means the updater for our app won't run after download!
