Trying to add stuff to the system environment Path via batch, vbs or anything really.

This used to work in a .bat, but has stopped:

setx -m path "C:\addtopath;%PATH%" 

This used to work in VBS, but has also stopped:

Set WshShell = WScript.CreateObject("WScript.Shell") 
Set WshEnv = WshShell.Environment("SYSTEM") 
WshEnv("Path") = WshEnv("Path") & ";C:\addtopath"

This keeps saying invalid syntax when I try to modify the registry:

REG ADD "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SessionManager\Environment" /v Path /t REG_SZ /d "%path%;C:\addtopath" /f

I am really stumped on this one. I need a solution that will always work. I am running it as administrator, but it still not working.

Cheers,

    What do you mean by "used to work, byt also stopped"? Any errors or just fails silently?

  • How long is your actual PATH value? There have been limits on the maximum length IIRC.

  • Was getting: Default option is not allowed more than '2' time(s). It did not exceed maxlength.

try to add it into PATH using GUI, right click on My Computer select Properties, and find Environment Variables, then edit the value of PATH

In my case, I somehow had a " end up in the actual PATH value...

I had to type PATH into CMD, copy out the contents, and overwrite it with setx PATH "contents here". (Of course, don't make any mistakes when you do this.)
