WinError 193 %1 is not a valid Win32 application. az bicep

When I try to run az bicep version I'm getting this error

The command failed with an unexpected error. Here is the traceback:

And the same error I have running all az bicep *** commands.

I tried to reinstall azure cli. Did not help. I deleted py related paths from PATH env variables. That was a suggestion from some github issue page.

Solution

  • The most likely cause of your error is that the bicep executable installed by Azure CLI is corrupted. See Issue #2364 on their repository.

    As described in this comment you can clean up the %USERPROFILE\.azure\bin directory and run az bicep install to get it working.
