ASPSuite encounters an error message when checking for updates, “The deployment identity doesn’t match the subscription.”
Probable Resolution #1:
The security certificate of the installed version of ASPSuite differs from the one in the new package. Due to limitations of the Microsoft Click-Once deployment it is necessary to use the Control Panel to manually un-install the currently installed version and then install the latest version from the download ASPSuite page. Ensure that you have a license with valid maintenance current on the machine before updating.
