Install binaries for that conanfile:

> conan install conanfile.txt -if conan-vc142 -s os=Windows -s compiler.version=16 -s build_type=Release -o *:shared=True -g virtualrunenv -r conan-center

Call created environment bat:

> conan-vc142/activate_run.bat
The input line is too long.

The problem is in PATH= env variable that gets filled with paths to every bin/ directory containing .dll files from installed libraries. activate_run.ps1 does not have this problem:

PS Y:\> .\conan-vc142\activate_run.ps1
(conanrunenv) PS Y:\>

I have not yet, but the mentioned fix was simply about removing extra envvars. The original problem comes from a single envvar being too long - AFAIK this is yet to be changed.
