I've got this legacy software that only allows you to run one copy at a time, it detects that you have another session opened and it won't allow you to open a second instance. The problem is this is a cpu intensive program and it only use a single core. Is there any hacks or tweaks so I can trick it and open more than one instance? This would allow me to retire about 5 servers... I'm using Windows 2008 R2. I had to use cff explorer to enable the use more than 2GB RAM as the program crashes when it tries to use more than 2GB.
