Hello everybody, I hope can help solve this problem, when trying to open a
file excel 2007 in excel 2003 gives me the following error:

this file was created in a newer version of microsoft excel. The file has
been converted to a format you can work with, but the following issues were
encountered. The file has been opened in read-only mode to protect the
original file.

- this workbook uses more rows and/or columns than are supported in this
version of excel. Any data outside 256 (IV) columns by 65,536 rows will not
be opened. Any formula references to data in this region will return #REF!
error.

I try to installing the FileFormatConverter and ConverterPack and still with
the same result.

It may do something or plan will have to install office 2007?

Greetings
