We have Office365 CTR, with Skype for Business 2015 installed. AFAIK, this is only happening on this one PC, that happens to be a Surface Pro 3 with Windows 8.1 installed.

When you initiate a Skype-to-Skype call, it appears to start to work, but it hangs and eventually crashes Skype. Every single time. This goes for incoming audio calls too.

This is a fairly new Surface Pro 3, almost nothing else but the default programs are installed. I have removed Office using the fixit tool and reinstalled. The audio/video drivers seem up to date, and the test in Skype settings works fine.

This is the error from the event log:

Activation context generation failed for "C:\Program Files\Microsoft Office 15\root\office15\lync.exe.Manifest".Error in manifest or policy file "C:\Program Files\Microsoft Office 15\root\office15\UccApi.DLL" on line 1. Component identity found in manifest does not match the identity of the component requested. Reference is UccApi,processorArchitecture="AMD64",type="win32",version="15.0.0.0". Definition is UccApi,processorArchitecture="x86",type="win32",version="15.0.0.0". Please use sxstrace.exe for detailed diagnosis.

Any help would be much appreciated.
