Friends, esp Tamar,

I am in happy possession of a new Surface Book, running Windows 10, which is delightful – except that I can’t make the msys64 installation work, which is crucial for GHC.  Can any of you help?

· I install it from here: https://sourceforge.net/p/msys2/wiki/MSYS2%20installation/, which seems to be the canonical place.  The actual 64-bit exe seems to be msys2-x86_64-20160205.exe.

· Installation goes fine

· But when I launch the “MinGW-w54 Win64 shell” from the Start menu, the screen flashes as if it is briefly putting up a window, but then the window disappears.

· Each time I do this the task manager shows that there is another running ‘mintty.exe’.   But it has no visible window

Does anyone have any idea what I can do or how I can investigate?  I can’t do any GHC development without this!

Thanks

Simon
