Can I have both 2.79 and 2.8 on my system? Will one interfere with the other? I have Blender 2.79 on my Windows 7 system.  

I want to install 2.8, but I'm completing some courses which use 2.79.

If I install 2.8, will it automatically replace 2.79?

Will they interfere with one another?

Thanks.
You can install multiple versions of Blender alongside without them interfering.

They will each have their own Preferences and scripts folder. On windows, there will be a folder for each version.



You can also use a Blender version without "installing" it by downloading the portable version.
