Windows Server 2008 triggers a security warning when trying to execute BlackFog because it is using code signed with a SHA-256 Authenticode certificate.
Windows Server 2008 requires a patch to accept modern applications signed with the more secure SHA256 Authenticode certificate. Microsoft released an update for Windows 7 and Windows Server 2008 R2 to support kernel-mode code signed with a SHA-256 certificate.
The recommended operating system software update is available from Microsoft TechNet: Microsoft Security Advisory 3033929.
Error Code 6:
After applying this patch you may also get Error code 6 when trying to load the application. You can see this within BlackFog’s log file. This means that your system requires a further patch to make sure it can load drivers using Driver Framework 1.1. This is documented in Microsofts knowledge base where you can download the patch for your machine.
