Export release build never completes

[mark21549]

Installed Flash Builder 4.7 64 bit, now projects won't export. I complete the packaging settings and click finish then it just sits there with the progress bar moving. I left it going for an hour but nothing, not even an error message. In the task manager the disk activity drops to zero after 20 seconds.

Operating system is Windows 8 Pro, 6Gb ram.

Tried creating a new workspace and a new desktop project which exported ok. I then tried copying the source files into the new project and re-export release build, now the same result, just sits there doing nothing.

Turns out it was Zone Alarm Anti Virus, uninstalled and all works ok.
