I have xl95,xl97,xl2003, & xl2007 all on the same partition. Best to install
earliest first but be sure to put in SEPARATE folders.

With office 2003 I could open worksheet with an wks extension. I can not
open these documents in 2007. Is it possible to install excel 2003 and
have
both versions of excel on same system?
