After updating I get an error window "Cannot start the application". The window contains the text "Application validation did not succeed. Unable to continue."

The "Details..." button is disabled (greyed out).

How van I find out what went wrong?

Thanks in advance!

Hello Fred,

Did you update Add-in Expry? Your add-in? Microsoft Office?

Could you send me a screenshot of the error message to the support email address? Find it in {Add-in Express installation folder}\readme.txt.
