Problem
I'm looking for a way to open multiple instances of an application in Windows 8.1, such as FastStone Image Viewer, which does not seem to have an option to enable multiple instances.
My goal in this particular instance is to be able to use FastStone Image Viewer to open as many instances as I need. So if I need a side-by-side comparison of two images, I could just open two images and view them side-by-side. A lightweight application that's always-on could work, but I'd like to see what else is available.
Workarounds
The only way around this I personally know of is using Sandboxie to sandbox the app and have multiple instances of it open thinking it's running by itself.
Question
Are there any other mechanisms for enabling this without installing a wrapper app?
