Export SCUP Self-Signed Certificate on Server 2012

Last week I had a problem. It was not possible to export the WSUS Publishers Self-signed Certificate with the private key.

WindowsServer2012_ExportPrivateKeyNotPossible   WindowsServer2012_PrivateKeyIsAvailable


To solve this issue, you have to grant permission on the private key file in the file system to your user. Per default only the WsusCertServer and the System account have access to it. The files could be found under:


There are several ways to determine the correct file. I mostly compare the creation date of the certificate and the creation date of the file. Normally the permissions look like in the next screenshot.


First you have to take ownership of the file.



Then you are able to grant permissions according to your needs on the file.


After that you can go back to the Certificate Console and export the certificate with the private key.
