I've installed the Microsoft Office 2007 Compatibility Pack and Service Pack 2 on client machines. In one case the user reports he can open .docx files successfully but is unable to open .xlsx files. Has anyone else seen the same issue? If you have can you trace it back to a certain issue? Any input would be appreciated. FYI: the system is XP Pro SP3 running Office XP.
Is Office XP updated to the latest Service Pack ? Microsoft KB Reports:
FWIW I was also facing the same problem, and in my case I asked the Author of the file to save it on Office 97-2003 format and sent it across to me.
