tricking installers

[machoman013]

Anyone know how to trick installers like the new AVG 7.x final free editions to install under a server OS like Win2k3 Server? I tried going into registry under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\ProductOptions

and changing it.. of course windows started bitchin' about license violation... i know of NTswitch but that's perm thing... 2k3 goes back to XP if in workstation mode.. I just need a temp trick to make installers that are 'workstation' only to install... for anyone who knows what I'm talkin' about... after 2k3 server modified.. no one goes back to s***ty XP or 2k
