Workaround for “Package does not support server operating systems” with Orca MSI editor
I recently tried to add the Windows Media Player 11 FireFox plugin (wmpfirefoxplugin.exe) to my Windows Server 2008 Enterprise Edition machine and was disappointed to see the below dialog warning me of the fact it wouldn’t install on a server operating system.

Not one to cede easily I opened Sysinternal’s PROCEXP.EXE, found the MSI handle, made a copy, and used Microsoft Orca to edit he MSI and remove the requirement. The package installed and works great.



If you use Windows Server 2008 as your workstation you might want to consider these same steps for any installation that fails around O/S verification. The warning, of course, is that the software might truly not work as expected. However, most of the times it seems to run just fine for me.
