How I get to the services section.

Settings
Control Panel
Administrative Tools
Services

mine is listed alphabetically
scroll down to the Remote Procedure Call (RPC) mine is set to started & automatic

while there double check the Windows Installer - mine is set to manual, but you could try setting it to automatic.

to change these double click the name and a pop up will come up and make the changes there.

then reboot and try the cd one more time???
back later errands to do...
