Failing to set up environment for 64-bit compilers from SDK v7.0

I'm trying to set up the 64-bit SDK compilers from the MS SDK v7.0. The install section of my appveyor.yml file looks like this:

  - "powershell appveyor\\install.ps1"
  - '"C:\Program Files\Microsoft SDKs\Windows\%WINDOWS_SDK_VERSION%\Bin\SetEnv.cmd" /x64 /release'

But I get the error:

"C:\Program Files\Microsoft SDKs\Windows\%WINDOWS_SDK_VERSION%\Bin\SetEnv.cmd" /x64 /release
29'Cmd' is not recognized as an internal or external command,
30operable program or batch file.
31'REG' is not recognized as an internal or external command,
32operable program or batch file.
33'REG' is not recognized as an internal or external command,
34operable program or batch file.
35The x64 compilers are not currently installed.

It looks like somehow cmd and reg are not being recognised as valid commands within the batch file. How could that be happening?

The actual build I want to do is more complex than this, as I only want to configure the 64-bit compilers for some of the build matrix (the 64-bit Python environments). So the full build uses a batch file containing the SetEnv call, but I get the same error there.

If it helps, the full failing build is at

Any suggestions gratefully accepted - I'm baffled.

    I don't know what's the problem with a script for SDK 7.0, but the one for SDK 7.1 works:

    "C:\Program Files\Microsoft SDKs\Windows\v7.1\Bin\SetEnv.cmd" /x64

    Yes, it's odd. Unfortunately, to build artifacts for Python 2.7, I need to use the v7.0 SDK. I'll install the two SDKs locally and see if I can see why they are behaving differently.

    I've just checked this on a local SDK v7.0 install, and I get the same error. Looks like it's a microsoft bug :-(

    Maybe it could be fixed somehow, for example changing Cmd to cmd?..

    It seems like running the script via a batch file that includes "setlocal
    enabledelayedexpansion" fixes the issue.

    Great finding, thanks! This is worth moving to KB area.
