Don't reinstall - you'll just end up in the same place. I actually saw this on my own machine, and something is messing with security. To put it back to the way it should be (and have it work), do the following, in this order:

Cluberti - love the clear graphical instructions!
I get a very similar error message to donaldormond here:
The machine-default permission settings do not grant Local Activation permission for the COM Server application with CLSID
{C2F03A33-21F5-47FA-B4BB-156362A2F239}
and APPID
{316CDED5-E4AE-4B15-9113-7055D84DCC97}
to the user NT AUTHORITY\LOCAL SERVICE SID (S-1-5-19) from address LocalHost (Using LRPC) running in the application container Unavailable SID (Unavailable). This security permission can be modified using the Component Services administrative tool.
I (foolishly?) followed your step by step instructions and all went well until Step12. The "Edit" buttons are greyed out and none of the "Use Default" or "Customize" buttons are selected - nor can I select them. I retraced my steps and all's good (i.e. machine still working as well as ever). Is there a simple fix you might be able to suggest?
Hi Teaboy
The error you are getting is slightly different to the one on the first page that is why it is greyed out. Read my last two posts and you will have your error fixed in no time
