Here is a great utility to manage your DCS install.
Application Goal is to Provide a GUI for Users as an Alternative to Complex Command Prompt Command Lines.
(Note: this utility is for the Eagle Dynamics' Distribution of DCS World, It will not function w/ the Steam Distribution)
Once you get it setup its a really powerful tool and will help you manage DCS version rollbacks and updates much easier.

If you need help setting it up, tag myself or Hedgehog in discord it will only take a few mins to get it up and running!
