How add certificate to the trusted Publishers With Installshield

[sylviepuaux]

I have created an Addin for Excel, a DLL of UDF functions plus a dedicated ribbon menu.

As some users require signed addins, I signed the DLL with a certificate (.PFX) issued by an authenticated certification body.

I generated a Kit with InstallShield and signed our DLL and the Setup with the .PFX.

However Excel still displays a security warning: Enable Content. I have to  manually add it in the Trusted Publishers.

Of course, I would like to automate it via Installshield.

My question is: how can I use InstallShield to add my certificate in the Trust Center (trusted publisher section)?

Best regards

Hi @sylviepuaux ,

Though adding certificate to trusted Publishers store can be automated using below methods:(Any one can be put under Pre-Build event as well)

• Executing certmgr with necessary command line parameters as given in https://docs.microsoft.com/en-us/visualstudio/deployment/how-to-add-a-trusted-publisher-to-a-client-computer-for-clickonce-applications?view=vs-2019 as prebuild event
• Using powershell cmdlet to import pfx into store.Reference link:https://dev.to/iamthecarisma/managing-windows-pfx-certificates-through-powershell-3pj#add-a-certificate-as-trusted

But Installshield has signing support for limited stores such as Personal,Enterprise trust,Trusted  Root CA & Intermediate CA.So it might not be possible as of today.

Since store based signing doesn't allow fixed entries(varying Thumbprints),it can't be put into any events as well.

Thanks,
