 I borrowed a template we completed a while back to start a new form and we now always receive the message below. No biggie for me and my coworker, we just say "OK" and move along. I want to unprotect a copy to send to someone. The Microsoft article (https://support.office.com/en-us/article/Help-protect-a-form-template-s-design-1f80a2c3-b8a5-4b38-8773-45cc517127bf) instructs me to go to Tools > Form Options > Category > Advanced > Enable protection. I do not have the "Enable protection" option under Advanced - I have IP 2013. Here's the message I want to get rid of. Alternatively, can the user just select "OK" and go on his way?

 

Here is my Form Options screen:

 

 Yeah, it is weird, because they removed that option and then you have these old templates that you can't change. I'm pretty sure if you save it as source files there is something you can remove in the manifest to get rid of the message - I'll try to find a protected template later today and see if I can figure out what you'd need to change. But yes, just select Ok and make your edits. The message is just a warning - it won't block you.

Found it. :) Save your form as source files, and search manifest.xsf for allowCustomization. It is probably set to no. Change that to yes and save. Then right click manifest.xsf and select design to open in design mode, File > save as to pack those files back up as an XSN.
