"DotNet SDK not found" error -- not related to Radzen

Serge_Solntsev · November 11, 2021, 1:03pm

Today I updated Radzen to 2.64.0 and install Visual Studio 2022 and .Net 6

And now Radzen cannot run an application, Output message:

dotnet: Could not execute because the application was not found or a compatible .NET SDK is not installed.

dotnet: Possible reasons for this include:

dotnet: * You intended to execute a .NET program:
The application 'watch' does not exist.

dotnet: * You intended to execute a .NET SDK command:
It was not possible to find any installed .NET SDKs.

dotnet: Install a .NET SDK from:
.NET Downloads (Linux, macOS, and Windows)

How to debug this?

What will happen if you type dotnet —info in your console?

And what is current version? dotnet —version

Serge_Solntsev · November 11, 2021, 1:55pm

I need to re-install SDK... something went wrong during VS update probably...
Sorry, my fault.


C:\Users\SSS>dotnet --version

  * You intended to execute a .NET program:
      The application '--version' does not exist.

Solved by fixing PATH variable.
There were two dotnet installed for some reason: in "Program Files" and in "Program Files (x86)"
The (x86) was old garbage. During .Net6 installation the PATH was modified such that wrong (x86) dir became before good one.

Now everything is Ok:
