This is UpdateActivationEnvironment() failing. This call definitely works and we use it on our machines. However, it returns an error if the argument-array is empty. I fixed this in -git now [1]. It sounds like you're hitting this. If the fix doesn't help, please let me know (should be in rawhide by tomorrow). Thanks a lot for the report!
