I recently upgraded from MS Office 2003 to MS Office 2010. I have tried to load the XlXtrFun.xll add-in for Excel 2010 since I need it for alot of my older spread sheats to work, and for some reason it won't let me.
It keeps prompting me that its not a valid add-in. I have redownloaded the file from the site and its still not working.
Is there something I need to do to make this load properly or is it now obsolete?
Any help is much appreaciated.
