My Excel installation is outdated, what does this mean?
NumXL installer checks for the existing excel installation and compares it against NumXL minimum requirement for compatibility issues. This is done to ensure a seamless operation of our add-ins within Microsoft Excel.
Currently, older Excel 2007 pauses a compatibility issue with NumXL and, it is mandated to apply the latest service pack (i.e. service pack 3).
