Been meaning to share this for awhile now, back during the platinum dupe I worked out how to run two accounts on one computer to do everything I needed to do.
First step: Install Attached file ("SandBoxie")
Step Two: Follow sand boxie instructions, run it, select Vanguard.
Step Three: Look at where it starts copying all your vanguard files when it repatches, basically it will want to create a new Vanguard directory to emulate from.
Step Four: Stop letting it patch/copy files etc, it takes forever to do it through the vanguard launcher, go copy and paste your original vanguard folder into the place where it was putting the files before(in sand boxie directory)
Step Five: Once you got all the files in both locations, load em up and play!
It does take a bit of playing around with to get it to work but it is not hard, I got it working within 30mins.
Enjoy being able to dupe by yourself with two accts now
ps: Told you all it was possible! You all said we had to get VG devs to change the code of the game but NO, proof at last I can do this
