There is a known fault in the Adobe marketplace add-on installation process which may result in a blank window displayed for some users using a Windows operating system, or a message which says:

The ‘PageProof’ extension could not be loaded because it is not properly signed.

For example, you may see this:

Blank panel in Adobe

Solution: Run your Adobe applications as administrator (just once):

Step 1

Click on your Start menu and scroll to your Adobe applications

Step 2

Right-click on Adobe Illustrator (for example) and choose More > Run as administrator, then open the PageProof add-on.

Right click on your Adobe Application, choose More, Run as administrator

Step 3

Repeat for each Adobe application.

Note: You only need to do this once per application.

Step 4

Re-launch your Adobe application, and the PageProof add-on will show your dashboard content.

If the run as administrator option does not work, try:

Step 1

Navigate to c:\Program Files (x86)\Common Files\Adobe\CEP\extensions.

File directory navigation for Adobe CEP extensions

Right mouse click the folder PagePoofCC and select properties.
