I think the following or a variation should do it. I was only able

names with them in my environment.
split(system('set ProgramFiles(x86)', '=')[1]
gets the value and
system('set ProgramFiles(x86)') =~ 'not defined'
will evaluate to true if the variable is not defined.
Not quite. You get hit by Windows *#$&#ing command-line quoting.
This works for me:
:echo system('set PROGRAMFILES^(x86^)')
In the past, I've solved very similar problems with batch files [1]
and Bash scripts [2].
The parentheses in the environment variable name are asinine.

Thank you for your answers. I think a simple
let l:pf = system('Echo %ProgramFiles(x86)%')
if l:pf == '%ProgramFiles(x86)%'
...
will work well enough.
Thank you,
