Instructions for installing Smoothwall on a Hyper-V machine


When I try to install an SP12 on HyperV I get the message that the CPU does not support the 64 bit extension the Smoothwall requires, although this is a modern Intel CPU. Is there a HyperV setup setting that needs to be enabled in order for the extensions to be seen by the Smoothwall?


If you are installing a Smoothwall system on HyperV and during the install an error shows that the CPU does not support the 64 extensions required, please disable Processor Compatibility mode for the Smoothwall host.

The knowledge base article from Microsoft below shows where to find this setting. The Smoothwall host needs to be powered off to change this setting.
