Problems after 1.2.7 Update

[nebuluski]

I am getting this error after updating to 1.2.7 (not the Open Beta and not Update 1).

 

If I launch using SP Launcher it crashes with this error:

 

Problem signature:

Problem Event Name: APPCRASH

Application Name: Launcher.exe_DCS

Application Version: 1.2.7.23097

Application Timestamp: 52b97dcf

When I launch using MP I can get onto a server and use sim.

 

Any ideas how to fix this?

 

Please Note I have a separate install of 1.2.7.Open Beta Update 1 which works fine on same PC so prerequisites must be OK (DX9c and C++ etc)
