A “flat” certificate, without the certificate chain path included, is required for signing with InstallAnywhere.

In order to sign a Windows target using InstallAnywhere, it is necessary for the certificate to be exported flat. In other words, the certificate chain path cannot be included. This is normally a default option, so it must be disabled. If the certificate chain path is included, the builder will report: “Code signing failed with following error: Unable to sign.”

The certificate can be exported graphically within Windows or with the cmdlet Export-PfxCertificate within PowerShell.
