Tor on flash drive won't run on other computers

I downloaded tor onto a flash drive using my ACER laptop and it works fine. When I try to run it from the same flash drive on my HP laptop it won't run and keeps saying 'The proxy server is refusing connections'.

I'm not a programming whiz so I looked online but the resolutions didn't help or I couldn't understand them.

What other information do you need to help?

Thanks
