So I finally set aside a whole day to do my freaking taxes and sure enough Microsoft Excel is NOT working.

Whenever I open an Excel document Excel Always closes, sometimes within a matter or seconds. Sometimes within 5 minutes. The point is it crashes.

I tried to open the control panel to repair it but without success.

I'm using an old old old version of Office I believe it's 2006. I use Word on a daily basis without problems.

How can I fix Excel?

Can I download a trial copy of Excel? I only need it for 24 hours!

Whatever recommendations you make please keep in mind I do NOT want it to interfere with Word since it's working fine.

I'm using Windows 7 Professional.

Thanks.
