Hi,
mickysace, and welcome to the forums.
Vista by itself does nto come with an Office suite pre-installed (OEM *computers* may, but Vista itself does not) and reading on the forums, it is possible that OpenOffice.org's Calc function may not work as well.
From
[Solved+Issue] Converting QuattroPro .qpw files (View topic) • OpenOffice.org Community Forum the suggetion is to download a trial version of Quattro Pro from Corel and convert all your files to Excel format, which can then be opened in the OO.o Calc program, or (of course) ini Excel itself.
