It sounds like your're already half way there and you have Vista which means your office 03 is upgradable if you havn't already had it upgraded.
The Microsoft Windows XP include this version of the Windows Installer in the operating system and will prompt you when available to upgrade office. If for some reason your vista hasn't upgraded office automatically then the latest version of Windows Installer is available as a separate download at the following locations: Windows Installer for Windows 95, 98, and ME Windows Installer for Windows NT 4.0 and 2000
Download the Update for Microsoft Office Outlook 2003 (KB2449798) to apply some minor bug fixes.
blah blah blah, don't worry about any of that for now...
You will know for sure that you need to update office if you copy from excel and the special paste option that opens a microsoft office excel object option are not options when you right click to paste in word.
SOOOOOO, when you right click to copy your excel doc in excel then right click in word to paste and the special paste option isn't displayed with the other paste option then office will need another upgrade.
If special paste option appears when you right click.....read on and good luck!
To embed an excel sheet into a word document you can try these steps:-
1. In Excel, click on the chart and do Edit > Copy (or, click on the chart and do ctrl-c). Or, select the cells you want to appear in your Word document and do Edit > Copy or ctrl-c.
2. Switch to Word
3. Now, click on Edit > Paste Special and choose Microsoft office excel chart object......
If all of that worked and you want to link your Excel doc and the Word doc (so the Word doc will convert and save whenever you work on the Excel doc. All editing/changes will be ''linked'' then click the Paste Link option). And click OK.
Oh, and if you want to hide any gridlines click on table->and click on hide gridlines.
Hope this helped and good Luck with it
