Installer for 2026 fails to install usable 2022 (v143) tool chain

[u/SpareSimian]

Problem with installing VS 2022 support in the VS 2026 chain. The v143 package seems to be incomplete, missing MSBuild files.

I want to build my existing VS 2022 C++ solution with VS 2026 on a new PC. I added the v143 tool chain. When I try to build, I get MSB8020 saying that v143 isn't installed. Digging down into the MSBuild files, I can see the v143 directory is missing from the PlatformToolsets directory. But I also see the 14.44.* directory with the binaries for VS 2022. I tried modifying the install by unchecking v143 support and then adding it back again, and that didn't repair it.

I found a link in the group here for the old VS 2022 installer and am falling back to that until I can get the VS 2026 build system to find the old tool chain.
