Hi,

They will work fine together, when you install 2007 make
sure you choose the custom install and check the
do not update option.

I have a class that will be utilizing Excel 2007 in the spring, but my
office
still uses Excel 2003. They have provided me with a copy of Office Std.
2007
so I can download Excel 2007, but I am unsure if I can operate both
programs
on the same system. ie. 2003 for work & 2007 for class. Any input would
be
appreciated.
