Just Lost two WD 500 platter drives that were made and bought around the same time 2 years ago. I have most of my Fallout save games backed up, but Nexus Mod manager was on one of the dead drives. My main rig specs are: Asus z97 motherboard, GSkill 16g Ram, EVGA 960 Titan 4g, WIN 7 OS, Intel 4770 processor. This PC has been flawless for Skyrim and Fallout and the drives that were lost were just data drives, my OS runs separate from a Samsung EVO SSD. I have cleaned out any instances of NMM across the 3 drives I have, but the program "hangs" after it is installed and told to run. Administrator does not seem to matter. I have tried each of the three drives one at a time, to no avail. One of them is a new WD 1TB that replaced the two dead drives. I also updated my Windows net Framework to 4.6.1. I did this because I was able to run Fallout 4 and load / install the NMM on a much older Win 7 machine I have as a test and it all worked well. The problem is that PC is too old to run Fallout 4 with mods. I need the NMM to run on my main rig and it will not at this time. I have reinstalled Fallout 4 and Steam, and can play in "vanilla mode". I need NMM to manage and run the mods to enjoy the game. Any help would be great, I even tried moving the working version of NMM from one Win 7 machine to this one and it still will not start. No error messages post, NMM just "hangs" with no action taken. Thank you so much for any help. Been a member for years and this is really got me dead in the water.
