Install a pfx certificate in a users store in Windows using WiX

Question

Please, can someone provide me with a WiX snippet or solution for the mentioned scenario. I need to include the pfx file in the WiX msi and the user will download my msi to his machine via the internet explorer and Click install and I need also the certificate to be installed on his machine.

Answer 1

You need the Certificate element. It is part of the IIS extension for wix, but can be used for non-IIS related installations also.

You need to

1. declare a prefix for the iis namespace, for example like this in the root Wix element:

   <Wix xmlns='http://schemas.microsoft.com/wix/2006/wi'
      xmlns:iis='http://schemas.microsoft.com/wix/IIsExtension'&gt;
   

2. Embed the PFX file as a binary stream in your install package. Add a Binary element under the product element like this:

   <Binary Id="MyCertificateBinaryStream" 
      SourceFile="c:/path/to/mycertificate.pfx" />
   

3. Declare a component with a <iis:Certificate> element, for example like this. Look at the documentation, you need to fill in some more attributes. Note that you don't need CertficatePath if you use the BinaryKey attribute.

   <Component Id="MyCertificateComponent" Guid="MY-GUID-HERE">
      <iis:Certificate Id="MyCertificate"
         BinaryKey="MyCertificateBinaryStream"
         ... some more attributes ...                  
      />
   </Component>
   

4. Activate the IIS extension by adding the option -ext WixIISExtension option when invoking the wix command line tools. If you use visual studio, this is just a matter of adding a reference in your wix project to WixIISExtension.
