I've made several portable programs using the PortableApps Launcher Generator. They all work fantastically, EXCEPT that for programs that open files, neither file association nor direct-launch (drag and drop the file onto the .exe) work.
As an example, I have associated .zip files with my 7-zip portable. However, double-clicking on a .zip file only STARTS my 7-zip portable, it does not load the file.
I'm sure that there is some setting somewhere that I'm missing to allow the launcher to pass the parameter to the program, but I can't find it for the life of me.
Please note that I am *not* having problems actually associating filetypes, or with drag and drop within the program. That, unfortunately, is all that Google and searching this forum turned up.
