A few days ago I installed (or tried to install) Hamachi as I wanted to play private games with my friends on Gmod. We're all relatively new to Gmod. My friends managed to install it with no problem, but mine hasn't even begun installing yet, despite the fact I tried to install it before they did. The status bar of the installation has been empty for 3 days now, and the fact that I can't cancel the installation to restart it doesn't help either. I don't know why this is. Have I run out of memory on my pc? Do I need to buy a new one in order to install it? Is my pc too old? I've only been playing on the pc for a few months,and I'm really not sure what to do.
