I was thinking about the same thing, but TeamSpeak is not running as administrator, and I tried both the 64 and 32 bit versions of TeamSpeak, both had the same behavior. While I'm writing this though, I'm thinking it might have something to do with TeamSpeak being installed in the "C:\Program Files" folder, and WideClient living in my "C:\FlightSim" folder. I assume that might make the program run with different privilege levels, but then why did it work with TeamSpeak2, as well as other programs installed in the "Program Files" folder? I guess it might be a Windows mystery that no-one will ever figure out :lol:. I will experiment a bit, see if it will work without running WideClient as administrator (which I don't really mind, except in principle).
Edit: It appears my hunch was correct, I installed TeamSpeak3 in my "C:\FlightSim" folder, and now it works without running WideClient as administrator, with both the 64 and 32 bit versions of TeamSpeak3.
Best regards,
