I just downloaded and installed version 10 on my Windows 7 64 bit computer. It meets all of the system requirements. I attempt to open Mathematica but it just doesn't. I can open the kernal but just not the actual program. I went to the task manager to look at the processes and they're just stuck at about 5,500k memory. I tried restarting my computer, uninstalling and then reinstalling, and opening as administrator. Nothing so far has worked. I'd really appreciate it if I could get some help with this. Thanks.
