I got an NW2010 list workflow that I exported from our dev farm, and imported to our prod farm. The workflow contains an InfoPath start form. The form itself is very simple; it only contains three start variables on it.
I have published the workflow on our prod box, but the InfoPath form itself is apparently corrupted (complains the form contains features that cannot be published. Nonsense, but whatever...) If I change the workflow to use the default form instead of the InfoPath form, the workflow functions properly. I want the InfoPath form, though, because I use it to post instructions for the customers, and also, it just looks better.
The problem is, there seems to be no way to delete that corrupted InfoPath start form. No "New", no "Delete", etc. It's just there. Before I try ripping it out via SharePoint Designer, I ask the Nintex universe, how do you go about removing a corrupted InfoPath Start Form?
