The solution mentioned above doesn't work for me.
Change language, restart Macbook, error again, change language back and forth, restart every time, it just doesn't work.
I was installing same app - Flash Professional CC 2014.
I got the same error
-------------------------------------- Summary --------------------------------------
- 0 fatal error(s), 1 error(s)
ERROR: DW039: Failed to load deployment File
-------------------------------------------------------------------------------------
So, same problem, same question.
