Set the safe for scripting and safe for initialization value in the registry

If you cannot recompile the ActiveX control, but the control developer classifies the ActiveX control as safe for scripting and safe for initialization, you can use one of the following registry values to mark the ActiveX control as safe for scripting and safe for initialization:

• {7DD95801-9882-11CF-9FA9-00AA006C42C4}
• {7DD95802-9882-11CF-9FA9-00AA006C42C4}

For example, if the CLSID for the ActiveX control is {A697E83F-3B53-11D1-8AE4-006097ED2008}, you can add one of the following registry values to mark the ActiveX control as safe for scripting and safe for initialization:

• HKEY_CLASSES_ROOT\CLSID\{A697E83F-3B53-11D1-8AE4-006097ED2008}\Implemented Categories\{7DD95801-9882-11CF-9FA9-00AA006C42C4}
• HKEY_CLASSES_ROOT\CLSID\{A697E83F-3B53-11D1-8AE4-006097ED2008}\Implemented Categories\{7DD95802-9882-11CF-9FA9-00AA006C42C4}
