Hello K,
This could happen if the certificate you are using to sign your setup package is not a trusted one on the related machines. Or if the target machine has no internet connection and Windows Installer fails to verify online the digital signature.
Please have a look on our
Why do I get “Error 1330: A file that is required cannot be installed because the cabinet file has an invalid digital signature”? FAQ.
One of our customers also had a similar issue and the problem was that he reverted to a snapshot of the virtual machine that did not have the updated root certificates.
Hope this helps!
Best regards,
Liviu
