when I install the 32 bit teamspeak version, the install runs fine but
when I try to start teamspeak no gui ever appears and the process is removed shorty thereafter
from the process list.

When I install the 64 bit version of teamspeak, the installation runs fine but when I start teamspeak I
get an error "Teamspeak 3 cannot write to the configuration file! You can use Teamspeak but all settings will be lost"
If I click on ignore a second error comes up: "No Teamspeak 3 Client installation directory found".
After that I'm able to use TS 3 but no configuration is saved and I cannot hear any sounds.

Both times I made sure to let the configuration be saved in my files.
