I regret to inform you that the Online Activation Kit is currently not compatible with PHP 8. The reason for this is that one of the components we use, Flourishlib, is no longer supported by its author and has not been updated to work with PHP 8.
However, we are aware of the importance of compatibility with the latest technologies and are working on a major overhaul of the Online Activation Kit for HTML Executable. This revamp involves replacing the outdated flourishlib with the widely used library called Laravel.
Unfortunately, it’s not feasible to manually update the kit to be compatible with PHP 8 without doing this extensive overhaul. While we don’t have a definitive timeline for this upgrade, please rest assured it’s one of our top priorities once HTML Executable 2023 is out.
The development team has finished addressing and correcting all the issues. We are currently updating the installer and conducting our internal tests, which have highlighted a few last-minute minor issues, hence the slight delay. It should be just a matter of days now.
