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.
This add-in is a free-download from the site you mentioned. The site is active so I'd suggest an email to the support address on the website (bottom of any page) will get you all the information you require...
However, I note the Op system requirements only go to XP, and does the Office version. It's possible this simply won't work under Office 2010.
