I installed .net 6 but the cmd says net 6 is not installed

C:\Users\Lenovo>dotnet run --project SonicHybridRsdk.Build
It was not possible to find any installed .NET Core SDKs

You might have installed the .NET 6 Runtime rather than the .NET 6 SDK. Try this: https://dotnet.microsoft.com/en-us/download/dotnet/thank-you/sdk-6.0.302-windows-x64-installer

i installed the sdk, not the runtime:

Weird. Open a command line tool and do the following:

echo %PATH%

You should have the following:

Then execute

dotnet --list-sdks

you should have one of the following:

C:\Users\******>dotnet --list-sdks
6.0.100-rc.2.21505.57 [C:\Program Files\dotnet\sdk]
6.0.101 [C:\Program Files\dotnet\sdk]
6.0.302 [C:\Program Files\dotnet\sdk]

If not, check if you have any folder with the name sdk in C:\Program Files\dotnet.

i have one, 6.0.302

[DonZombpepoGames]

but the console says there are not SDKs

C:\Users\Lenovo> dotnet --info
