cefclient.exe means: "Chromium Embedded Framework".
It is most likely used to display the library and/or keep the connection to the online store (I'm just guessing).

The good news is that in my Computer (Linux/Wine/Bottle/P12) cefclient.exe does not cause problems. May be that in P11 an older version is used. I can not say because I have only ever used P11 in a VM.

If you use Bottle: Try to change the settings a little bit.

For testing purposes you can install P12 (a trial version is available on Posersoftware.com, it can be used for 21 days without restrictions). P12 also uses cefclient.exe and works for me, as I already mentioned.
