How to create verification that will validate if Reportviewer is installed?

Question

I need to create a check that will validate the installation of Report Viewer on the user’s machine. If not installed, I need to receive this information to make a treatment present a message to the user and facilitate future maintenance.

I’m doing a lot of research, but I’m not getting any results.

Can anyone tell me how I can create this check, or has some content to indicate where I can consult?

You can check in the register:

public bool IsInstalled()
{
    RegistryKey registryBase = RegistryKey.OpenRemoteBaseKey(RegistryHive.LocalMachine, string.Empty);
    if (registryBase != null)
    {
        return registryBase.OpenSubKey(@"Software\Microsoft\ReportViewer\v2.0.50727") != null
            || registryBase.OpenSubKey(@"Software\Wow6432Node\Microsoft\.NETFramework\v2.0.50727\AssemblyFoldersEx\ReportViewer v10") != null
            || registryBase.OpenSubKey(@"SOFTWARE\Wow6432Node\Microsoft\ReportViewer\v10.0") != null;
    }
        return false;
}
