Tamar
Thank you! Yes, it's in c:/msys64
Since I wrote more odd things have happened.
1. I just left the machine for 10-15 mins and lo! the shell windows opened up. It just took a loooong time.
At this point, starting a new shell no longer took a long time. It all seemed to be working.
2. I then ran pacman -Syuu as instructed on the installation page: https://sourceforge.net/p/msys2/wiki/MSYS2%20installation/
The log of what happened is below. There are numerous failures involving Cygwin, which I do not have installed, at least not so far as I know. I do not know if these failures matter.
3. After this step, starting a shell failed altogether with "c:/msys64/mingw64_shell.bat is not recognised as an internal or external command". And sure enough, there is no such file. Presumably it existed in step 1. So perhaps step 2 deleted it?
4. As you mention, I then tried msys2_shell.cmd. It worked -- with a noticeable delay of 5 seconds or so.
So I'm less stuck than before but
* should I worry about all those install errs
* how can I debug what's happening with
that long delay
* Should I nuke the start menu shortcuts that
the msys64 installer so carefully installed
in favour of msys2_shell.cmd?
Thanks
Simon

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://na01.safelinks.protection.outlook.com/?url=https%3a%2f%2fsourceforge.net%2fp%2fmsys2%2fwiki%2fMSYS2%2520installation%2f&data=01%7c01%7csimonpj%40064d.mgd.microsoft.com%7c2801115a7b2e43ebd2da08d39e63ba89%7c72f988bf86f141af91ab2d7cd011db47%7c1&sdata=qXzbQdt3AGrhl3oL48tbGsUgpz%2b6q9uCCMrlfn145Wg%3d, 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
