Tried AWD, AWD2, obj, whole scene, and also selected, but although it has a prgress bar which goes up to 100%, the destination folder is empty..

Any ideas?

Hmmm…. Could it be a filename length issue?

Just tried the same but saving to desktop and it worked fine…

No it’s a write privilege issue. I presume you use the wonderfull world of Windows 7 or 8, where loads of directories do not have by default write access. That’s why desktop is allowed, its public (for you as humble Windows user) by default.

This is on my todo to implement a fix to trigger an error, as its one of the unsupported/implemented features in AIR. No way to check if the app has write privileges and no errors triggered back on failure.
