I presume you have the office software package (CD). Go to control panel, add-remove, Microsoft office, select the support option, then select repair. if this fails it will be necessary to uninstall Office completely and re-install, your documents will not be deleted,just the progam. Terry
Thank you VoG and Terry Brown for your quick responses. Actually, every time I need to even look at a document in Word, I get the error run-time message. Yes, I obviously can't print as well, but I can't even read the document! Sorry to confuse you!
