I wouldn't be so sure it's a Sonar bug just yet, it could be latest UAC code can't handle latest C++ libraries and needs to be updated..
I still strongly recommend you try and rule this out before you contact any support, you can then tell them you tried all this before they suggest it...
* Turn off antivirus temporarily.
* Try running Sonar as administrator (fixed similar errors before).
* Update your audio interface device drivers and firmware (just in case).
* Get windows update fully up to date (you appear to have a C++ error here with MSVCR120.dll so well worth trying).
Thanks...
