Things to consider
- all parts must be downloaded in the same folder
- that folder must not have restrictions. so the default Downloads folder is not recommended.
- you must extract only using 7zip. Anything else will corrupt the contents when extracted
- your drive must be healthy. I've seen people complain that they get corrupted files all the time even after redownloading everything multiple times. Make sure you at least download on a healthy drive. Right click on 001 -> 7zip -> Test archive
You should check the zips md5 hashes and compare them do these using this tool
You must be registered to see the links
. If you get different values then your downloaded files are corrupted
