I was curious if the server components for Pharos Uniprint 8.0 and/or 8.1 are supported on Windows Server 2008 R2 (64-bit).

The Pharos 8.1 CD image contains a "Documents" folder that contains both an "Upgrade Guide" and a "Planning and Installation Guide."


Starting on page 14 of the "Planning and Installation Guide" is information on server requirements (including system, hardware, SQL) and page 22 discusses 64-bit server support and VMware.


With regards to the statement on page 22 of the provided PDF: "Pharos components are not officially supported on VMware 64-bit virtual machines due to hardware compatibility issues with these virtual machines."

The issue is with VMWare and certain Guest OS and VM image combinations.




Pharos 64-bit VM support is subject to that supported by VMware. Some versions of VMware do not support specific combinations of guest operating systems and host processors.

For example, with older versions of VMware, running a 64-bit guest OS on an AMD Opteron processor may work, while running the same guest OS on a first generation 32-bit Intel Core Duo would result in random crashes and other unpredictable behavior.


Pharos installed on VMware in unsupported configurations will have various forms of instability.

Customers will need to establish that their specific combination of host OS, host hardware, guest OS and VMware configuration is fully supported by VMware before they attempt to install Uniprint.


Here's a quick breakdown.
