For example, let's compare registry key values to demonstrate:
%Test ~ Will not allow you to compile
%%Test ~ Will allow you to compile
It will only install %Test on the box. The extra percentage is to notify Wise Installer that the % is not intended to reference a variable.
Note: This behavior will happen in registry keys, INI file, Insert Line in text file, Display Message, Custom Dialogs or in any location where a variable can be referenced.
