Windows 7: Scanner requests Server Manager

This is a weird one: I start a scan like I always do.
I get the preview, but then instead of finishing, the scanner stops and I get a message:




"Please install Desktop Experience from the server manager."


I don't have a server manager. I am running Windows 7 Ultimate SP1. Also, I have no idea what experience a desktop would give me.


I tried doctoring around with switching Windows 7 features on and off (web services, Media Player) because those were mentioned in connection with a Desktop Experience most frequently, but this changed nothing.


What I HAVE done a few weeks ago, is remove all instances of the built-in Photo Viewer, as it always kept creeping back as default.

Can manually deleting anything called Photo Viewer impact the scanning process?



Any pointers?

Thanks

Here's a screenshot



Is there a way to re-install the Photo Viewer, which I suspect is the cause of this?

I have started getting this error message too.
Interesting idea about Photo Viewer.... I was having trouble with .COM surrogate errors.
However, I did uninstall, and then reinstalled with a clean version from my roommate's Windows 7 computer.
So I have photo viewer again on my computer, and it works good now.

But this scanner error is same as yours - the pre-scan shows the image, activates the scanner, but then this error message shows up.

Well, since I have not received any feedback, I have simply given up.
