The package may fail to install due to certificate chaining errors, even if the signing certificate is not self-signed and the root certificate is in the root store of the local computer. In this case, there might be an issue with trust for the intermediate certificate authorities. For more info about this issue, see Working with Certificates. If you determined that the package couldn't be deployed because the signing certificate isn't trusted, don't install the package unless you know where it originated and you trust it.
If you want to manually trust the app for install for example, to install your own test-signed app package , you can manually add the certificate to the local computer certificate trust from the app package. After this manual addition, you can see that the certificate is now trusted in the Certificate dialog. Look for the serial number of the certificate that you installed.
This number is the certID. We recommend that you avoid manually adding root certificates to the local machine Trusted Root Certification Authorities Certificate Store. Having several applications that are signed with certificates that chain to the same root certificate, such as line of business applications, can be more efficient than installing individual certificates to the Trusted People store.
The Trusted People store contains certificates that are considered trusted by default and so aren't verified by higher authorities or certificate trust lists or chains. By adding a certificate to local machine certificate stores , you affect the certificate trust of all users on the computer. We recommend that you install any code signing certificates that you want for testing app packages to the Trusted People certificate store.
Promptly remove those certificates when they are no longer necessary, to prevent them from being used to compromise system trust. If you create your own test certificates for signing app packages, we also recommend that you restrict the privileges that are associated with the test certificate. Follow the prompts to burn the CD.
