Suzanne,
I don't know if the following will be helpful to you, but maybe you could give me advice. I would like to know if what I did could be problematic for a computer in my office. I experienced a similar problem as did "Goonerbu". Here were the actual error messages.
Different messages for different files.
Excel error - "The file is corrupt and cannot be opened" error on office 2010 Excel while opening .xls files
Word error - Word experienced an error trying to open the file. Try these suggestions.
* Check the file permissions for the document or drive.
* Make sure there is sufficient free memory and disk space
* Open the file with the Text Recovery converter
When I checked the Trust Center Settings as recommended above the file Excel2007 workbook was not check. The only items that were checked were the following.
- Excel 4 Workbooks
- Excel 4 Worksheets
- Excel 3 Worksheets
- Excel 2 Worksheets
- Excel 4 Macrosheets and Add-in Files
- Excel 3 Macrosheets and Add-in Files
- Excel 2 Macrosheets and Add-in Files
HERE IS WHAT I DID TO RESOLVE.
- Click file>options
- Click Trust Center>Trust Center Settings
- Click Protected View
- Uncheck the following boxes
- Enable Protected View for Files originating from the Internet
- Enable Protected View for Files located in potentially unsafe locations
- Enable Protected View for Outlook attachments
Is there any problem with what I did to resolve it?
