Htmlexe 2021 running errors

Hello, I updated latest htmlexe 4.x.x to vestion 2021, and ran into several issues right away.

  1. With content protection active I was unable to start my publication. I am running Windows 10 Home 21H1


Also, I was unable to activate my publication. After I disabled protection, activation screen opened. Generated activation key is not recognized by the publication.

Content protection requires you to have Desktop Window Manager enabled on your computer. See this for instance:

You can also configure HTMLEXE not to exit if Content Protection fails.

For the activation, are you using with online activation or normal registration keys?

I use normal keys
