Hi @AlvinLopez,
I'm not sure if you are aware, but you posted your question to the global community of Instructure products (Canvas and others). Canvas itself is a website, so you shouldn't need any special software for Canvas itself. If you're required to use other software packages for a specific class, you'll probably want to contact your teacher directly (email, phone, canvas inbox, etc) to discuss options with them if you don't have access to any other computer with install/admin rights.
Hope this helps a bit!
