Error using vcpkg

[albaropereyra22]

I am using Visual Studio 2026 and I am getting the following error when I try to run the commands in the wiki.

Here is the error I get:
error: in triplet x64-windows: Unable to find a valid Visual Studio instance
Could not locate a complete Visual Studio instance
The following paths were examined for Visual Studio instances:
C:\Program Files\Microsoft Visual Studio\18\Insiders\VC\Auxiliary/Build\vcvarsall.bat

When I try the following command;
./vcpkg install jsoncpp

Please advise,
Thanks,
