On a serious note, I checked wikipedia and confirmed the official site is https://www.rarlab.com/, which means you likely purchased a cracked version (unless they’re a reseller, of course).
Once in while I run into multi-gigabyte zip files that free tools like 7zip and infozip do extract some files from, but clearly aren’t working properly. For some reason the commercial programs like WinRAR are able to handle those. The free options don’t seem to work as hard at handling all the edge cases created by buggy implementations out there.
The performance difference on massive files can be dramatic, too:
If you’re just an average user that needs to compress and decompress a few files here and there, 7zip works great. But if you’re working in IT, you’ll probably find you need it, sooner or later. Whether or not you buy a license:
If signature is from major CA and name of signee matches expectations, then all is well barring major cybersecurity incident on software vendor side.
Get file checksum from trusted third party and compare with generated checksum of received file manually. Oldschool and not used as much, since process cant be automated.
Second file in you original post has no digital signature whatsoever, so dont trust it. It has been repackaged by the seller.
Personally there has been absolutely no reason to buy winrar or winzip this or last decade, you can use 7zip instead. Winrar offers nothing that OSS does not and it probably survives only thanks to brand recognition alone.
Unless too onerous, just do chargeback and if possible then report the site them to winrar. Scammers like this should not be able to do business online.

What I don’t really understand is why people do that “why did you buy Winrar lol” thing.
I mean, something you’d use regularly, you should support it financially.
Everybody wants everything for free now, tools, music but don’t mind spending 1000 bucks on a completely overpriced CPU or GPU, just a weird time to be in right now.
It’s the use of WinRAR that seems fairly strange to most (its popularity has declined dramatically over the years), not that you’re willing to pay for something. Nobody would bat an eye if you said you donated to 7zip.
The rest of the comments are just the usual meme that nobody pays for shareware… In the same vein as “Nobody drives in New York… There’s too much traffic.”
