A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
Response is not applicable to windows RT. If you follow the instructions linked above you find that there are no programs listed on the computer.
The solution I ended up with was to accept all associated file types for the program. You can do this by going to control panel\Set Default Programs\Set your default programs, select Excel and then select Set this program as default. This will associate all 24 files types listed under the excel program.
My personal feeling is that one of these file types may be in conflict or associated with another application in windows, but then again I'm not a programer so what do I know. If that is the case and I need to unassociate a particular file extension from excel I'd appreciate the feedback.
Thanks.
