v3.5.2 has the same problem. Who developed that strange setup system?
I start calling a Windows release "Operating System" when SP1 is out.
Before usually neither the operating system nor all the applications I need are stable on the new platform.
BTW: AFAIK the RunAs is still working the same on XP, Vista and Windows 7. There is a high probability that this bug affects all versions. Will test it if I get a chance.
