Microsoftnet Desktop Runtime 80 X64 2021 ((better)) -

Quick Clarification

"80" likely means version 8.0.
Version 8.0 was first released in November 2023, not 2021.
In 2021, Microsoft released .NET 5.0 (end of life May 2022) and .NET 6.0 (Nov 2021 — LTS).
If you see “80” paired with “2021” somewhere, it’s probably a typo or mislabeled file. Do not trust an “8.0” package claiming a 2021 copyright date — check official Microsoft sources.
