HTMLEXE Manual activation not working on HTMLExe published ebook

I have purchased the HTML Executable Activation Kit and its been working fine with HTMLExe. We updated the HTMLexe to 2022 and the ebooks we publish using the new version of html2022 can not be activated manually (offline). What happens when someone activates manually as the ebooks can only be activated Online at this moment.

Can you describe the problem you’re getting?
