Microsoft Office 2010 is installed on my PC (Dell Studio XPS8100, Windows 7). Another member of the household has asked whether she can install Microsoft Works 9.0 on my PC, now that her PC is on its last legs. (She greatly prefers Works over Office, for its simplicity and because of her long-term familiarity with Works.) If Works 9.0 is installed onto my PC, would this cause problems for Office 2010, Works 9.0, and/or my PC? If so, are there workarounds? Thanks.
