I did some testing on both 32bit and 64bit.
Playonlinux 32bit needs to have wxPython version 18.104.22.168 put into the slack-required file. As the dependencies are still satisfied with wxPython 22.214.171.124 but it will not work with that.
However, after installing wxPython I was able to install and run a couple applications.
Playonlinux 64bit complains about missing 32bit openGL and says there may be problems.
Tried a couple things, I can't get anything to run in 64bit.
Error in POL_Wine
Wine seems to have crashed.
