For all those lighting designers who use ETC's Expression Off-Line Editor or any off-line editor:
Download the off-line editor installs you would like to add to your menu.
Make sure you have plugged in your drive that you use, but don't start portable apps menu.
Install the editor like you normally would, but when you get to where you want to install it, select F:\PortableApps\ExpressionOff-LineEditorPortable\ where F is your drive letter and ExpressionOff-LineEditorPortable is the new folder created.
Once it installs, just start your portable apps, and select the program from the menu.
This is legal because the software is free to use from there website.
