How to get environment variable in 64 bit Windows?

Question

Is there any way to retrieve the environment variable in 64 bit machine. I already have %abc% which returns me variable in 32 bit machine, but doesn't work in 64 bit.

My Mistake: How can I get through command line not through programming language?

Answer 1

Try System.Environment.GetEnvironmentVariable("abc")

Answer 2

In PowerShell you'll get environment variables with

$Env:abc

This is independent of bit-ness.

In cmd you can get environment variables with

%abc%

this is also independent of bit-ness, so it would be nice if you'd elaborate what exactly you tried and where it failed and in what way.
