Well first off are you using RH Server to host this content? If not, then you’re wasting your time with producing WebHelp Pro – it’s specially formulated to work with RH Server.
What do you mean that you have confirmed the .cpd is in the source folder? Are you running some sort of source control? If so, I don’t believe that the .cpd is supposed to be subject to that – it should remain on the local drive.
1. Yes, I am using RoboHelp Server.
2. Never mind. I was trying to check easy things off the list - files actually being in the source folder. I think I made things more confusing.
To make things weirder, I just closed the RoboHelp application, but kept the Smart Publishing Wizard open. I then published, and did not get the error. So it looks like Robo is accessing the .cpd and is conflicting with actually publishing?!
For one thing, the CPD is a SOURCE file and should never be among the OUTPUT files. So it's odd that you would be attempting to publish the CPD.
I'd be investigating how the publish operation is set up because something is definitely wrong.
Thanks for your help - something's definitely wrong behind the scenes. I'll do some poking around.
