Im using file.openWithDefaultApplication() to launch native OS shortcuts, eg chrome.lnk instead of chrome.exe, with AIR 3.5.

It works fine if the .lnk points to a 32bit program, or if I use the 64bit .exe instead of the .lnk, but if I try and launch the 64bit version via the .lnk, nothing happens.

Anyone had any problems with the file.openWithDefaultApplication() function and 64bit shortcuts? Pretty weird edge case I guess.
