My perpetual license does not give access to the version I have installed

After installing XLSTAT, you can get the following error message if you have a perpetual license but you have no longer access to free upgrades and support:
When ordering a perpetual license, you got one-year of free upgrades and support, and the possibility to renew it each year.
This means that your license never expires but once your upgrade & support term has been reached you have no longer access to new releases.
In this case, you will need to download and install the latest version of XLSTAT to which you have access with this perpetual license.
Please contact our support for assistance during this process.
