Welcome to the forum.
You will just need to distribute the CHM. No app is required
but you may need to register some DLLs. I'll leave a CHM user to
comment on that.
The reason you are getting that message is because you are
viewing the CHM from a network drive. Move it to your hard disk and
it will be OK. See CHMs Not Displaying Properly on my site.
Your RH project should be on your local drive too.
