First, extract the setup that comes with DevCPP by right-clicking and using 7-zip to extract.
Cut/paste the content of /$PLUGINS/ and /$OUTDIR/ into /bin/ so that the executables are inherently available without adding environment path variables.
Install any 3rd party packages that you need for your clients.
In wise package studio, I created a folder in /Program Files (x86)/ titled "Bloodshed DevCPP" and placed all files and folders in there. Created a shortcut on the desktop, and a shortcut in the start menu to devcpp and package manager.
Then, I set all of the standard file-type association to devcpp.exe including but not limited to (.cpp, .c, .h, .rc, .dev, .devpak (packman.exe), .hc, etc...)
This in my opinion is the best way to repackage this as it allows you to include many things by default such as includes, libraries, configuration modifications and more (on top of building patches for updates.).
