How to create totally empty environment variable


I'm trying to create an empty environment variable so I have entered these settings but it doesn't work.

When I enter a string as the value of even a space it does.

So this doesn't support adding real env variables ?

Is there another way to accomplish that ?

Try creating an empty environment variable either from a Set command in a Command Prompt Window or through the Environment Variables panel in the Control Panel.  I think you'll find that Windows doesn't allow this.  Setting an environment variable to a null string is the equivalent of deleting the variable.  InstallShield is simply "enforcing" this "lack of capability".
