Excel reports won't open - everything else seems ok


I'm getting error message: "An unexpected err has occurred:
Error Number: 1004
Error Desc: 'C:\Users\Bob\Documents\My ESPlanner\xxxxx.xls' could not be found. Check the spelling of the file name, and verify that the file location is correct.

If you are trying to open the file from your list of most recently used files, make sure that the file has not been renamed, moved, or deleted.

How to use Libre Calc instead of Microsoft Excel? (Where's the .xls file?)


It appears that ESPlanner builds a .xls file and attempts to load into Excel when the "Excel" option is chosen for Report output. However, I use Libre Office rather than Microsoft Office. When I try to create the Excel view, the program only throws out some error messages. The easiest workaround would to be to manually open the .xls file in Calc - if I could find it. Thanks
