I found this in registry:
"C:\Programfiler\Autodesk\AutoCAD Map 3D 2012\Setup\Setup.exe" /P {5783F2D7-A002-0409-0102-0060B0CE6BBA} /M ACADMAP /language en-US
How do I get it to run silently?
either using MSIEXEC (easiest option)
msiexec /q /x {5783F2D7-A002-0409-0102-0060B0CE6BBA}
or
"C:\Programfiler\Autodesk\AutoCAD Map 3D 2012\Setup\Setup.exe" /Q /P {5783F2D7-A002-0409-0102-0060B0CE6BBA} /R ACADMAP /language en-US
(which will remove the language pack as well)
