More info: From the log file captured when applying the patch as Guest User, I can see the problem --
MSI (s) (84:AC) [13:12:31:684]: Certificate of signed file 'C:\Windows\Installer\5b124f33.msp' differs in size with the certificate authored in the package I have double checked that the same certificate that I sign the .msp with using signtool is the same certificate added to the PatchCertificates node in the WiX source file in the msi (and via Orca I can see the binary is actually in the MsiDigitalCertificates table). Is signtool the correct tool to use? Do I need to include any certificates in the msp -- I am just signing the msp at the moment. Do I need to include anything else in the msi?
