    0hi roberto.fiocchi The affected versions are 9.0.7 and 9.1.0, other versions don't have any issues. 
 The issue is now resolved, and here's the quick fix: https://abp.io/support/questions/8990/unregistered-version-of-Eziriz%27s-NET-Reactor#answer-3a18ca49-409a-d43e-0df5-8df4b150c93dOnce released, my application will not be modified or updated. Can you confirm that offline everything will work even after years and that there are no licenses or anything that will block my application? Thanks
