I am testing Windows 2008 R2 as a desktop OS. But Oa in my company must be installed in it.
Unfortunately the "Administering the ActiveX Installer Service in Windows 7" document by Microsoft states:
The ActiveX Installer Service is not included in Windows Server® 2008 R2. If you attempt to install an ActiveX control from your Web browser on a computer running Windows Server 2008 R2, a User Account Control dialog box with a yellow bar will be displayed warning you that the publisher is unknown.
How can I make it work?
