Helper variable that contains the working folder path for the post-installation "Run application" action. It is used by the final RunApp action in the predefined UIFirstInstall action sequence on the Actions project page.
Usage
You can refer to this variable as <UIRunAppDir>. The variable is set through the Start in field on the User interface project page in InstallMate Builder, but you can also set it at installation time through a Set Variable action.
