Trouble installing the add-on from Adobe?
There is a known fault in the Adobe marketplace add-on installation process that 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:
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.
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.
Right mouse click the folder PagePoofCC and select properties.
Step 2
Select the Security tab and in Group or user names select your user name, then click Edit...
Note: You may need to enter a password.
Step 3
In Permissions for Users ensure Allow is checked on next to Full Control, then click Apply and OK to close the windows.
Step 4
Re-launch your Adobe application, and the PageProof add-on will show your dashboard content.
