Error 1920 while installing 3ds Max 2012 Service Pack 2

I noticed an Error 1920 while installing 3ds Max 2012 Service Pack 2 x64. Error 1920 is a Windows Installer error code indicating I do not have sufficient privileges to start system services.

A simple workaround:

run a dos command prompt as Admin, navigate to the location of the msp file and type:

msiexec /update 3dsmax2012_sp2_64-bit_enu.msp

Best regards.

Mental Ray errors

 If you notices these errors

// mental ray for Maya: using rayhosts file C:/Users/User/Documents/maya//maya.rayhosts

// Error: (mental ray) : Unable to load file: plugin.dll //

// Error: (mental ray) : cannot load plugin.dll, The specified module could not be found. //

using Mental Ray Satellites, probably the slaves don't have the plugin installed. A quick fix, if you don't need the plugin for the scene:

run Window -> Rendering Editors > mental ray > Shader Manager and unload the plugin:

Best regards.
