Shim errors for the .NET Framework version and platform support

Note This article introduces shim error messages. If you are an end-user, try the resolution when you encounter a shim error "You must enable the .NET Framework from the Windows Features dialog box." For any other shim errors, the target audience for the contents is the app vendor or developer, you have to contact the app vendor in order to let them know that there is a problem for this app.

Error: "You must enable the .NET Framework from the Windows Features dialog box"

This application could not be started. You must enable the .NET Framework from the Windows Features dialog box (from Control Panel, choose Programs, Turn Windows features on or off).
This issue occurs because the app is not configured in a way that makes it possible to determine the appropriate version of the .NET Framework runtime. The corresponding shim code is SHIM_GOTO_CONTROLPANEL.
To resolve it, enable the .NET Framework 3.5 which is an operating system feature on Windows 7 and Windows 8.

Error: "This application could not be started"

This application could not be started.
The app is not configured in a way that makes it possible to determine the appropriate version of the .NET Framework runtime. The corresponding shim code is SHIM_NOVERSION_FOUND.
You can't fix the configuration problem yourself. Contact the app vendor to resolve the issue.

Error: "It relies on a .NET Framework version that is not supported on this device"

This application could not be started. It relies on a .NET Framework version that is not supported on this device.

About shim error messages

When you start a Microsoft .NET Framework application, a shim program determines which version of the common language runtime (CLR) to load, loads it, and starts the application. If the shim encounters an error (for example, if it can't find a compatible version of the .NET Framework on the computer), it displays an error message with instructions. This article provides information about the error codes SHIM_NOVERSION_FOUND, SHIM_GOTO_CONTROLPANEL, and SHIM_UNSUPPORTED_PLATFORM.
