What Markbnj means is that there is a Help and Support Service that has to be running. To find out follow these steps:
1. Open the Run... dialog (Windows key+R or Start | Run...)
2. Type "services.msc"
3. Look down the list to see if there is a Help and Support Service
---a. If there is, see if "Started" is next to it.
------I. If so, then I do not know what is wrong.
------II. If not, ensure that it is set to something other than "Disabled" and start the service by right-clicking on it and selecting Start.
---b. If there is not, go to Control Panel | Add/Remove Programs | Windows Components. Look in the options for "Help and Support." You might have to click "Details..." on some of the listed objects to see it.
------I. If you find it and it is unchecked, then check it and then click OK.
------II. If you find it and it is already checked, then I don't know what is wrong.
