Thanks for the reply Joshua. I know that HS 2 wouldn’t be supported on Vista but I was checking to see if anyone had any success with it. As mentioned earlier, I’m not in a position to upgrade to W7/8 so if installing HS 2 has any serious consequences, I’ll just stay with HS 1 until the appropriate time. I know others have had issues with Vista but I’ve been running Vista Business 64 for years without any problems. In the future, I plan to install W7 on an SSD HD but that’s not in my budget presently. If I can get one positive testimony for HS 2 on Vista, I will try my luck. 
Thanks again!
