New Post: Task pane not loading in non Dev machine and getting error

I have created a com addin using Net Office and added a custom task pane (added WPF user control using ElementHost in Windows user control). I have added my functionalities and it works fine in developer machine.

I have copied all required dll files to non developer pc and am getting error saying "unexpected state in CTPFactory Available."

Getting below error:

Error
