Why dotnet --list-sdks does not show installed SDKs on Windows 10?

Question

I have Microsoft .NET SDK 5.0.102 (x64) installed on my Windows 10, but when I do dotnet --list-sdks nothing shows up? I could see the SDK installed from Windows Apps & features. Thank you.

Edit:

Doing dotnet --info shows the following

$ dotnet --info

Answer 1

Removing c:\Program Files (x86)\dotnet\dotnet.exe from global System Variables Path helps for me.

Answer 2

There are multiple .NET installations on your system and they are getting mixed up.

You have one installation that's x86 (C:\Program Files (x86)) - and has no SDK - and another that's x64 - and has the 5.0.102 SDK.

When you run dotnet, you seem to be running the x86 version.

The SDK you have installed is the x64 version.

You should try and figure out which architecture you need and uninstall the other one.

Answer 3

CHECK YOUR ENVIRONMENT VARIABLES!

I just ran into this issue and discovered that some how my C:\Program Files (x86)\dotnet\ environment variable was above my C:\Program Files\dotnet\ which meant that whenever I ran the dotnet command it was using the x86 version.

Answer 4

See Windows or Visual Studio can't find the latest installed .NET SDK

If the first SDK installed on the machine is a different bit size, you won't see the latest SDK
