When I play a track, it is locked by Helium - and won't be unlocked.
This might break scripts - for example when changing filetype and the script tries to delete a file that has been played before, the script will fail.
Even if I try to delete that file using the windows explorer, I can't until I close Helium.
I understand, that Helium locks files, which are currently in use, but it should unlock them afterwards.
Please retry with: http://files.helium.fm/helium_12.0.14252.0.exe
It should solve the locking related to the play operation.
