Microsoft Office 2003 Professional Edition is an must have application Microsoft Office. 2003, Full Version, MS Office, O, PC, PC Software Under 200MB. The memory card on my comuter was corrupted and needed replacement. My Microsoft Office Professional 2003 needed to be reinstalled. I could not find the original program.

Cal-osha Lock Out Tag Out Program. I could not find the original program. I tried to purchase it from Microsoft, but there was none available.only 2007.

I did purchase it online and installed it. There was no problem until I downloaded Microsoft Office 2007 and dedcided not to purchase it. Since then my Office program tells me that it is not authentic. I cannot access any help for 2003. Is this a virus or is it Microsoft giving me a problem?
