in reply to ENV PATH didn't take effect

I am afraid I am not qualified for the windows support, but my best guess is, the system variables do not get propagated to all users as you suspect.

I think, that should be the normal behavior.

You can modify your own PATH variable in Perl through the %ENV hash.

$ENV{PATH} contains the PATH, and you can modify it.

Subsequent shells or cmd prompts invoked by your Perl script use that information.

    Thank you for the response. In fact, I changed the Path variable using Perl by TieRegistry. The system path do changed. But the click-opened command prompt didn't. If it didn't propagate to all users, I've already logged in as administrator, why I should right click opened "run as administrator" to see this change is beyond my understanding. I expect after I added the PATH env, all users can use it, no need to set it manually any more.

      The change, if made permanent, may take effect after a logoff/logon.

      The environment on disk is copied to your live environment on logon.

      Changing the config on disk does not followup in memory right away.

      Cheers, Sören
