This is the most annoying error. Because Microsoft labels the 2021 update as a "new" product, Windows Installer sometimes gets confused.

From a security and performance standpoint, the move from 2019 to the 2022 generation was significant. The 2019 runtime, while robust, received security updates only as part of its support lifecycle (which ended for mainstream support in April 2024). The 2022 runtime introduced improved mitigations against speculative execution vulnerabilities (like Spectre v2) and better support for Control-flow Enforcement Technology (CET) in modern processors. Developers targeting the 2022 runtime could also leverage a more optimized Standard Template Library (STL), resulting in faster containers and algorithms. For end-users, however, the tangible difference is often invisible—unless a vulnerability is exploited, or a program runs perceptibly smoother on new hardware.
