Signing

Newer Windows operating systems have code signing embedded into their security. As such, AVEVA have begun signing .msi files and .cab files for installations which are not restricted to Windows 7 or older operating systems.

Unfortunately, the Administrative Installation process recreates and/or alters the source .msi file and removes .cab files altogether, thus removing any file signatures. Changes to a signed file always invalidates its signature.

In this release AVEVA have signed all dll's and exe's that are supplied. However in order to cater for installations where internet access is not permitted/available AVEVA provide a .exe.config file for each exe file that tells the operating system not to validate the digital signature. By default the installation is set to deploy the .exe.config to disable the digital signature validation. To enable digital signature validation the command line option CERTIFICATECHECK=1 should be set.
