I have tried everything
You haven't tried the last thing I told you to try
I have no idea how to do some of the things that were suggested
Then please explain what is you don't understand of my previous explanation about how to check which files were bad.
I need an installer that can just install correctly
The installer obviously works for everybody. But as I'm sure you probably noticed, it needs to download files and, as I already explained, the files are downloaded from the Cloudflare node closest to you and THAT particular node might still be outdated.
WHICH IS WHY, I posted precise instructions how to check which files they are, so we can do something to fix them at YOUR specific node.
. I either need explicit directions to make sure I do it correctly
Which is precisely what you have been given in my last post to you. If you don't understand some parts, then please explain again which they are, so I can try explain them better.
I do not know how to control what server my download comes from to make sure it comes uncorrupted from a cloudfair server.
That's not your job to know how to do that, yours is only tell me which file you got bad. Read my previous reply to you, which explains how to use a free utility to check the checksums of the files you downloaded. Just post the results, as user Mhbt Ba did.
