Download Microsofts Excel viewer from http://www.microsoft.com/downloads/details.aspx?FamilyID=c8378bf4-996c-4569-b547-75edbd03aaf0&DisplayLang=en
It's 9.9 Mb, and it says the estimated download time on a 56.6 connection is 25 minutes. You won't find a smaller one.
Maybe you've got some friend or family or work where you can download it via broadband and put in on a USB-stick?
I received an Email with an attachment that is an .xls file. I do not want/have MS Office. Is there a small (I'm still on dial-up) program download that will allow me to open/view this file? Have Exp.6 XP SP2-media ed. 2005 . Thanks for anyone's help!
