In this case, you can use one of the following flags to override SEM_FAILCRITICALERRORS: For example, if you have a native COM component that hosts the CLR and that is hosted in a process where SEM_FAILCRITICALERRORS is set, you may want to override the flag, depending on the impact of displaying error messages within that particular application process. However, in some scenarios, it is important to override the SEM_FAILCRITICALERRORS setting set by an application process. You can specify the SEM_FAILCRITICALERRORS flag to prevent the error message from being displayed.

Windows provides a SetErrorMode function that you can use to declare whether you want error messages to be shown as a result of code that runs within your process. (The ICLRMetaHost::GetRuntime method does not accept this flag, and does not provide any other way to display the error message.) By default, the error message is not displayed. You can include the METAHOST_POLICY_SHOW_ERROR_DIALOG flag to request an error message if the requested version of the CLR is not found. The ICLRMetaHostPolicy::GetRequestedRuntime method accepts a METAHOST_POLICY_FLAGS enumeration member as input. In either case, you can control this UI by passing flags to the activation APIs.

The user can choose Yes to go to a Microsoft website where they can download the correct. The following error message is typically presented in this situation. If the CLR activation system cannot load the correct version of the runtime that is required by an application, it displays an error message to users to inform them that their computer is not properly configured to run the application, and provides them with an opportunity to remedy the situation. CLR hosts should always consult these return values before proceeding with additional operations. The CLR activation APIs return HRESULT codes to report the result of an activation operation to a host. This infrastructure should not be confused with assembly binding logs, which are entirely different. The CLR provides logging infrastructure to help you debug CLR activation issues, as described in How to: Debug CLR Activation Issues. This article provides a list of HRESULT codes and explains how you can prevent the error message from being displayed.

If the requested version is not found, the CLR activation system returns an HRESULT error code from the function or interface that was called, and may display an error message to the user who is running the application. This situation typically occurs when an application requires a CLR version that is invalid or not installed on a given computer. In some cases, the activation system might not be able to find a version of the CLR to load. The common language runtime (CLR) activation system determines the version of the CLR that will be used to run managed application code.
