Unity won't install. What is going on?

I got the free version of Unity and I tried to install it. Close to the beginning of the installation I get a box saying that I lost the internet connection and either have to retry or cancel. I checked my internet connection while the box was open and I had a good connection. I was even able to browse the web. I click retry and the box immediately comes back (except for just one time where it didn’t). Pressing Cancel only brings up a bug report box with Abort, something else, and cancel. Hitting cancel seems to continue the installation. However, after seeing this process to the end, the only folder that showed up was the Standard Assets folder. I don’t know what’s going on but I would very much like to get to work on stuff and this “thing” is bugging the crap out of me.

[edit] I went back to it every day, and I noticed that it stops at 39992kb, or 3% of the install. I tried just getting the 32-bit editor instead of the whole installer, but then it says “page not found” if it doesn’t work, and the download fails if it does.

@Zagule’s answer on this similar question worked for me (please upvote their answer if this helps you):

It happened to me as well, and the issue was that it was buffering the download through drive C that was full (even though I installed to a different drive), and reached out of storage memory. When I cleared some space there it resumed fine. It used about 2 GB of buffer space.

If that doesn’t help, you can bypass the Download Assistant entirely by visiting the download archives page, locating the latest version, and clicking the dropdown for your platform:

(Replace Unity 5.2.2 with the latest version, replace Windows with your platform, and choose 32-bit/64-bit as appropriate.)
