Unable to preview PDF files in Windows 10 Explorer or MS Outlook with Power PDF

Issue:

Unable to preview PDF files in Windows 10 Explorer or MS Outlook with Power PDF

Resolution

This can happen if the necessary registry keys were not generated when Power PDF was installed.  Sometimes Windows Security prevents our software from modifing the registry during the installation. The resolution is to manually create the necessary registry keys.

Attached is a .reg file that creates the necessary registry keys.  Please note that this file contains the path to the installation folder for Power PDF in two places and it may need to be modified to match the path at the client site.  Specifically, the newest installation of Power PDF 30 puts two spaces between "Power PDF" and "30".  Be sure the path matches the system on which you are using this file. 

Installation Instructions

The file has a .txt at the end so it can be edited and emailed - remove this extension and click on the .reg file to merge it into the registry of the workstation. Once the registry file is loaded, open taskmanager and restart Windows Explorer.  The previews should be working now.
