CaGetEnv()

This function can be used in any generated jscript or vbscript custom actions.

This function gets the value of an environment variable. It requires minimal if any user permissions.

The function takes these parameters:

  1. The name of the variable.

  2. A boolean, pass "true" if you wish to terminate with an error if the environment variable does not exist.

EXAMPLE

<$VbsCaEntry "Install">
   PathVar = CaGetEnv("PATH", true)
<$/VbsCaEntry>
