Windows install error (Detected that the setup program has been called inside a Cygwin or MSYS2 environment)

[reedjones]

Trying to install on windows, getting this error:

Detected that the setup program has been called inside a Cygwin or MSYS2 environment. In particular, C:\msys64\usr\bin\cygpath.exe was available in the PATH. Since the setup program uses its own MSYS2 environment, and since MSYS2 does not support one MSYS2 or Cygwin environment calling another MSYS2 environment, it is highly probable the installation will fail. Please rerun the setup program directly from a Command Prompt, PowerShell, the File Explorer or directly from the browser Downloads if you downloaded it. Do not use Git Bash (part of Git for Windows) or anything else that contains an MSYS2 environment.

What do you see when you type: echo $env:PATH in PowerShell?

I have a bunch of stuff on path, why do you ask something specific you suspect I'm missing or? One thing relevant I found was I had 'AppData\Local\Programs\DkMLNative\usr\bin'
which I had added this to path, because whenever I run anything from 'AppData\Local\Programs\DkMLNative\bin' (which I had added onto path before as well) I got some error about missing: 'dklmvars-v2. or something' I never got anything to work

[jonahbeckford]

The error message you got is that you have a conflicting program in your PATH. Kinda hard to help you identify it if you don't tell me your PATH though.

[jonahbeckford]

You have both the following in your PATH:

• C:\msys64\usr\bin
• C:\tools\msys64

Having the first one in the PATH will definitely conflict with DkML (and other programs that use MSYS2). I'm not sure about the second but I think that will conflict as well.

The MSYS2 installer does not add itself to the PATH, so I'm guessing you did it manually or some other program did it automatically. Regardless, remove both of them from your PATH.

Root cause: Only one version of MSYS2 is allowed to be accessible to programs on your machine, so placing MSYS2 in the PATH is almost always "wrong". You can always launch MSYS2 using the MSYS2 recommended https://www.msys2.org/docs/terminals/ if you need your own private copy.

That worked, thanks for the help.
