First, there's no need to bump up a subject, since I've already pointed out to the other thread, it should have been pretty obvious that one contains everything we know about this issue.
The issue is NOT caused by any of our products, it's usually something bugged in your system, which is CAUSING Couatl.exe to crash (it's not the other way around, Couatl.exe is the victim of something else in your system which has gone wrong) which is either the VC++ runtimes or a problem with your Windows account, which was cured by all users in that thread.
Another user I've assisted with Teamviewer, had this error, which turned out to be caused by audio drivers with bugged support for the OpenAL standard sound library. A possible solution for this could be replacing/updating the audio drivers. Sometimes it's best to use the one supplied with Windows, sometimes it's best to use the ones by the sound card or mainboard manufacturer, there's no rule, one has to try.
