Re: install.bat in windows-arm64 not working

Sorry for the late response; I also do not really use the arm laptop, but I was testing my IDE and stumbled upon the error. 
I investigated a little further:

The output of your command inspect(os.uname()) is:
table={
 ["machine"]="arm64",
 ["nodename"]="LAPTOP-93YX-KB0",
 ["release"]="",
 ["sysname"]="Windows",
 ["version"]="",
}

So the (using my workaround) installed distribution correctly detects itself as arm64 and the install.bat script does this too, as:
echo %PROCESSOR_ARCHITECTURE% returns ARM64
and
echo %PLATFORM% returns windows-arm64

I opened the extracted installer zip folder as a VS Code workspace and let Github Copilot analyse the files. His response:
-----
In mtxrun.lua (line 4058), the platform detection for Windows ARM64 sets:
   bits, platform = 64, "windows-arm64"
So os.platform becomes "windows-arm64".
In mtx-install.lua (line 477), the lookup:
   local osplatform = environment.arguments.platform or nil         -- nil (no --platform arg passed)
   local platform   = platforms[osplatform or os.platform or ""]   -- platforms["windows-arm64"]
The problem: The platforms table in mtx-install.lua:106 has entries for "win64", "mswin", "windows" etc., but "windows-arm64" is missing. So the lookup returns nil.
On your x86-64 machine os.platform is "win64", which exists in the table — that's why it works there.
-----
And indeed, by adding the line
["windows-arm64"]  = "windows-arm64",
to the platforms table, the installer works (output: mtx-install     | platform : windows-arm64). I guess the entry was just forgotten to put in.. But I am quite confused that I am the first to notice this, as these days there are many windows arm devices around..

So I guess that was the issue and adding the platform table entry is the solution?
