I created a digital signature for my macros using SelfCert.exe. I am attempting to export the certificate to another PC. I follow the instructions found in the Certificate Manager Export Wizard and get this error at the finish:

Error exporting the private key. The private key may not be exportable.

The Certificate Manager Export Wizard seems to be designed to create a .pfx file based on a Personal Certificate with a Private Key; but it errors instead. Could find no help in MS Knowledge Base or White Paper - those sources confirm use of the Certificate Manager Export Wizard.

Can anyone help with exporting the Digital Signature Certificate? BTW FindFiles does locate any *.pfx or *.cer to 'copy' using Explorer.
