Even though this thread is 1½ year old:
I've been running Linux (OpenSUSE) on my computer for years, and I haven't managed yet to run CA on this machine - neither Wine nor PlayOnLinux has been working for me to make CA run.
The only workaround I found was: installing Windows on a virtual machine, and run CA there.
Tbh I think it's a pity that CA doesn't offer a Linux version as well, because I don't know any native Linux software that can count as an alternative.
