|Looks like your Office 2010 Student and Teacher version is looking for the installation source. Do you still have your Office install Disc? If you do just put it into your DVD drive E: and the installation will grab the files it needs.|
This is most likely caused by a office update that your received.
If you do not have your disc, you will want to download a shell extension manager and remove office shell extensions.
