can I get the 1.051 patch

I am a game design student and my school is running constructor with the 1.051 patch and I am running the 1.06 update on my home computer. Is there anyway to downgrade to the 1.051 version so that I can be on the same page as my school. I have very limited access to the school and do all of my work at home accept for the time spent at school for classes. I also learned on 1.051 and to be honest 1.06 interface although looks relatively the same I noticed a few differences. Any help will be greatly appreciated.
