Dave,

.pvk is a thing from the past. Modern operating system do not support this old certificate type any longer. The certificate will make it into your certificate store and then you have to export it to .pfx. You should always use the recommended browser (which supports Microsoft Authenticode). It depends on the Chrome version, but Chrom is definitrely not the recommended browser type.
