Our UA server calls application.CheckApplicationInstanceCertificate, which auto-generates a certificate.  When using the 1.4.371.86 UA library assemblies, the resulting certificate is generated with the provider, Microsoft Enhanced Cryptographic Provider v1.0.  When using version 1.4.371.91 assemblies, the certificate uses provider, Microsoft Software Key Storage Provider.

In the latter case, the certificate details cannot be viewed in the UA Configuration tool because cryptographic exception, "Invalid provider type specified" is thrown.  The cert from 86 works fine.  Of course, we'd like to use the latest stable release.  Any idea how to get version 91 to use the enhanced provider?
