Up until about a week ago, when I was designing a form in Lifecycle, I could click from the design tab to the Preview PDF tab, see the PDF preview of my form, then click right back over to Design view. Now when I click on Preview PDF, first I get a quick message like an Internet Explorer error saying "Navigation to the webpage was canceled." Then the form will open in Adobe Pro, but it's not really a preview. It is actually opening Adobe Pro. How can I get back to where I can just click back and forth between design view and preview?
While you try preview make sure that Adobe Pro services are not running in the
Go to task manager and check .
If any instance of Adobe pro is running , please stop it.
