Trademark Symbols Appear as Question Mark and Header Background Not Showing in Output

The trademark and other symbols fix has worked for everyone else so I don't see why not for you. Start a new project with just the defaul topic and test it there. Also try it with the About RoboHelp sample project.

If it still fails and the update was applied with admin rights, check Help > About says 2022.5. If it does, then I suggest for this one you need to go to Adobe Support. See https://helpx.adobe.com/contact/oenterprise-support.other.html#robohelp for your Adobe Support options. The email link tcssup@adobe.com is recommended as it reaches a team dedicated to Technical Communication Suite products including RoboHelp.

On the background image issue, I assume that worked in Classic. If it did, then raise that with Support as well. You could try saving it as jpg instead but you shouldn't need to.

Let us know how you get on.

I have assumed your project is on your local drive and you are generating to the same drive.

There is a thread about symbols not appearing correctly in CHMs. The issue was fixed in Update 5. See this thread to apply the update.

What background are you applying? CHMs are an old technology and may not support some backgrounds.
