I need step by step help on how to download Blender 3.4.
Does Blender 3.1 need to be deleted first?
Do I just add the 3.4 on my desktop so I have two Blender programs?
When I begin, do i choose Change, Repair, Remove?
Do I close down 3.1 before I add 3.4? Then delete 3.1?
You don't have to delete the versions, you can have them all at the same time. So you can have 3.1 and 3.2 and 3.3 and 3.4 all installed and it doesn't matter. You can even run them at the same time, have them open one alongside the other.
To download Blender, just head over to blender.org and head for download. There you can download the latest blender version which is in the blue square and if you want older versions you can see in the gray square that it says other versions.
