Germaine, when you installed OO, you checked a box you shouldn't have. Just
re-assign XLS files to Excel.

Hello:

I downloaded OpenOffice and it has taken my xls files hostage. I am trying
to upload existing xls files to Sharepoint, and am getting an OOo error
something like this (An API call existed abnormally). This is an OOo error
although the file is an xls file. Help.

Thanks, Germaine
