Error 'Application cannot be installed' when upgrading Content Station

When installing Content Station AIR, one of the following errors can occur:

Error 1:

"This application cannot be installed because this installer has been mis-configured.

Please contact the application author for assistance"

Error 2:

Sorry, an error has occurred.

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.

The reason for this is a new code signing certificate that was introduced in Content Station AIR version 7.2.3 and Content Station 9.7.0, making it impossible to upgrade the currently installed Content Station AIR version.

Content Station AIR has to be uninstalled first before a more recent version of Content Station AIR can be installed.
