How can I Install ActiveX in Windows 2008 R2?

Question

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?

Solution

I think that's just a warning. It's been a while since I've seen one, but it just asks you if you want to proceed or not.

Answering "yes" will install the ActiveX control.

@jazzson: what is "Oa"?

[MDMarra]

@Peter - Maybe he means OWA? Who knows.

So, wait, is this the solution you've found? Or is this an update to the question?
