Error "Your XLSTAT version must be reinstalled before activation"

Dear XLSTAT User,

Our license system has been recenty replaced by a new one.

If the below error message pops up when trying to activate your license, it means that you are using an XLSTAT version which was built based on the old XLSTAT license system. This no longer functions. 

The solution:
If you have a license with an ongoing maintenance plan , please download and install the latest XLSTAT version available at: If you have a perpetual license, but no longer have access to upgrades and maintenance, you can download the latest version you have free access to through your MyXLSTAT portal or contact our sales team at
