Problem

This error message appears when the /f parameter in the signtool command points to a non-existent file.

Solution

Re-run the SIGN+_Installer in the SIGN+_Package to install and copy the required files and use the newly generated command in the README.

Problem

This error occurs when the file has been signed using a non-trusted certificate (when the customer signs using the appviewx certificate) or the certificate is not imported into the windows certificate store.

Solution

Sign with a trusted Certificate or import the certificate into the windows certificate store and try verifying the file again using the signtool command.
