Adobe AIR error

Report · Sep 07, 2018

When I tried to install/update Scratch 2, I get the following error message:

The application cannot be installed due to a certificate problem. The certificate does not match the installed application certificate, does not support application upgrades, or is invalid. Please contact the application author.

I have uninstalled Adobe AIR and then reinstalled it, but I still get the same error message. I am running Windows 7 currently.

What can I do to, so I can install Scratch 2?

Thanks,

Keith

Hi,

Thank You for reporting the issue.

The problem could be due to the different certificate used to package the application for version 2. Please uninstall any already installed older version of the application(Scratch) and then retry installing the latest version.

Thanks!
