Solution Attempts: (rebooted several times throughout the following) 1. Verified the temp directory exists via "environmental variables". Removed all *.tmp from said directory. I have full permissions. No success 2. Created a new temp file and pointed to it via the "environmental variables". I have full permissions. No Success. 3. Uninstalled/reinstalled ESET nod32 antivirus4. Same error. No success. I'd like to isolate the error via procmon and filtering with ekrn.exe, but I am not having any luck. If someone could offer me some advice on procmon or another solution, I'd greatly appreciate it.
