Not sure if your win or mac or linux but if its windows set mumble or ts or ventrillo to run as admin fixes that issue with every game from happening...

If you want to run the 32 bit version on a 64 bit system

Check own architecture:
dpkg --print-architecture

Check if a foreign architecture is installed:
dpkg --print-foreign-architectures

sudo dpkg --add-architecture i386 && sudo apt-get update && sudo apt-get install ia32-libs

unzip file.zip ...
