2.3 and 2.4 problem

Hey.
I tried several times to download the upgrade 2.4 through 2.3 - but it got stuck after a while.
Then I stopped it. After several failed attempts when I run 2.3 the window closes immediately.
What is the solution to the problems?

Thanks

I overcame the problem.

I downloaded the standalone installer

alright, mate, sorry for that.
