Question re: upgrade process

So this is the first upgrade I’ll be doing and have a question. I’m running the Windows version … and I’m wondering if when doing a minor upgrade if i need to DL the package that has the JRE in it … I did the first time but (3.4.4) wondering if I need to dl the large file or if I could get by with just the non-jre file.

I always download the full version and archive it. That way if I need to reinstall or downgrade, I do not have to download it again. Better safe than sorry.
