It seems to work fine, except for `mtxrun.exe` (which isn’t downloaded
to `bin/` or to `tex/texmf-win64/bin`).
mtxrun.exe comes from the .zip file you download from the installers
page on the Contextgarden website.
Many thanks for your help, Bruce.
I knew, but I was downloading a Win64 distribution (with its binaries)
on a Linux64 OS (afaIk, `$HOME` is a Unix variable, `%USERPROFILE%` in
Windows).
Well I did wonder why you were using Unix syntax but saying the problem was with your Windows machine.
...
This was the reason why I invoked `./install.sh --platform=win64`.
It has never occurred to me that install.sh might be able to act as a file downloader. I thought the reason for being able to specify a version is for when the script is getting confused and failing to recognise the machine type.
...
Two minutes after sending my message, I downloaded it from
http://lmtx.pragma-ade.nl/install-lmtx/context-win64.zip.
Installation went fine (my Linux64 box doesn’t complain for Win64
binaries, since I don’t run them there).
But installation on which machine? Or do you mean "download" went fine? It's all very confusing.
...
On my Win64 at work, `mtxrun --generated` gives the already referred
message "Access denied" (well, in Spanish).
...
If that doesn't show anything unusual then try the icacls command. I
got the following output:>
c:\context\bin>icacls mtxrun.exe
mtxrun.exe BUILTIN\Administrators:(I)(F)

          BUILTIN\Users:(I)(RX)

I get the same output for both not working newest lates and working
previous latest (but in Spanish):

Okay, so it looks like the permissions are correct.

Try the above first and we can troubleshoot a bit more if the cause
still isn't clear.
To confirm that I speak of the same binaries (old and new) as you:

You can calculate checksums directly in Windows, rather than over a file share, by using PowerShell:

  PS C:\> Get-FileHash -Algorithm SHA512 C:\new\tex\texmf-win64\bin\mtxrun.exe | Format-List

I get the same as you do above for mtxrun.exe.
...
BTW, this made me realize that `mtxrun`, `context` and `luatematex` are
exactly the same binary.
Old worked and new didn’t. What worked for me were the 32bit binaries
(full install from
http://lmtx.pragma-ade.nl/install-lmtx/context-mswin.zip),
That definitely sounds like a problem with your work computer's configuration. If you are running 64-bit Windows then the 64-bit binaries should run just fine.

What do you get if you run

C:\> where.exe context.exe

It's the equivalent of Unix's 'which' command so will help determine if the .exe being run is the one that you think it is.
...
My Windows installation may be picky with the newest binaries, but I
think there may be something with them.
Of course, I cannot say what that might be, but something different from
previous compiliations.
Many thanks for your help,
Pablo
