Missing executable file when executing action on self-hosted runner

Describe the bug When using a self-hosted runner using an EC2 Windows instance, using the actions-rs/toolchain action in a step give me the following error:

Error: Unable to locate executable file: C:\actions-runner\_work\_temp\8bae825a-e905-492e-87b2-d7eef3178974. Please verify either the file path exists or the file can be found within a directory specified by the PATH environment variable. Also verify the file has a valid extension for an executable file.

@lionel1704 how did you download the runner package? does your runner has C:\actions-runner\externals folder? make sure you download the actions-runner-win-x64-2.286.0.zip package and not any of the others.

I’m currently dealing with this issue. I’m setting up my own Windows runner, and have installed rust/rustup/cargo on the box, and they’re available on PATH, and have restarted the actions service, and yet still hitting this error.

Has anyone here actually got this working?
