Builds with rust > 1.75 not working on windows 7 /8.1

[i300220]

Release 3.00B1 tested on Win 7 64. Doesn't start. No log produced: it crashes at start.
Release 2.03 which was build before rust 1.76 is OK

Rust stopped supporting Win 7/8.1 at V 1.76 last march. This is from an official rust source.

What are the options?

• On Win 7, if you don't already Visual Studio 2019 or 2017 installed, it's impossible to install.
• If I try to cross-compile on linux, the resulting executable doesn't start. It crashes with an error about missing api-ms-win-core-winrt-l1-1-0.dll. If I copy that dll to the dir, it crashes with a new error message. I anticipate, since the errors are revealed one by one, the incompabilities list is endless.

Already discussed a bit starting at https://www.audiosciencereview.com/forum/index.php?threads/analog-audio-crackling-filter-project.57670/post-2112758

See: https://github.com/HEnquist/camilladsp/releases/tag/v3.0.0-win7test
There is a separate build with rust 1.75.

Thanks so much. If we remove those 3 parameters from config, it works beautifully:

    #link_mute_control: null
    #link_volume_control: null
    #stop_on_inactive: null

I had to install camilla-plot manually though, windows being windows....
