As @irgendwer just answered you wthin the chat couple of minutes ago: Please use the 64-bit TeamSpeak 3 client from teamspeak.com.
Are you running a x64-based operating system on your computer?
What OS do you use? (win7/win8/win10)?i wonder how to look at it, but it's written to the computer that it is 64-bit.
And no, you can't run a 64bit program on 32 bit system, the other way is possible (32bit program on 64bit system)can I make compatibility on it?
