Sorry, still unable to build a release version!
By endlessly reinstalling Visual Studio Community 2022 I at last succeeded in installing it correctly. I didn't understand why it was failing so many times before nor did I understand why it was succeeding the last time. So now I have in the General->Platform Toolset line of my project indeed the same and wished for "Visual Studio 2022 (v143)". So I started again compiling an arbitrary file of my project first with "Debug" (succeeding) and then "Release" with error=TRK0005 Failed to locate CL.exe. It is a pity but I have to admit I failed also(to be surprised). I would have expected both debug and release compiler-linkers would be the very same! So because of my activities started so long ago I would have expected Visual Studio Community 2022 should have known itself - being installed yesterday - where to find everything. So I had to give up again. And again to report the community about my misfortune. I am using Visual Studio - I think - about (nearly) 30 years and never used any environment variable like PATH. Possibly it might have become necessary now. Still I can't build a release executable. By an unexpected fortune I was able te build a release version very recently on the 15th of August and after that not a single one unless the community can help me. I experienced this 15 August success as normal never expecting to remain unable to rebuild a release version so long! What do I do the wrong way? Thanks to the Community for so much patience!
