[wix-users] Can I have a Bootstrapper with optional MSI for a certificate?

Hi All,

I'm just completing a nice Wix burn bootstrapper with WPF UI which currently has only 1 MSI which does not need UAC.

I now think I have to install a certificate.  Is it possible for me to make a 2nd MSI for just the Certificate (Which requires UAC) and the bootstrapper only will use it and thus ask the user for UAC if it is missing?

I would like that the user only the first time needs to use UAC and then all further installs or updates would proceed without it.

I think I know how to add a certificate in the MSI.

 <ComponentGroup Id="MYCertificate" Directory="SystemFolder">
      <Component Id="Com_Certificate_New" Guid="{}" Permanent="yes" KeyPath="yes">
        <iis:Certificate Id="Certificate.CA_New" Name="myName" Request="no" StoreLocation="localMachine" StoreName="root" Overwrite="yes" BinaryKey="Certificate.Binary_NEW"/>

What would I need in the boostrapper to check if this certificate is present.  Or maybe I have to do something in the MSI as I can see in this post https://stackoverflow.com/questions/23372459/certificate-detection-installation-with-wix-installer

Thanks all for any and all help
