If any of you wish to silently install AutoCAD LT 2005 / 2006 use this commandline:

MSIEXEC /I %MSIFILE% TRANSFORMS=%MSTFILE% ACAD_SILENT_LICENSE=YES ACADSERIALPREFIX=xxx ACADSERIALNUMBER=xxxxxxxx ACADFIRSTNAME=xxx ACADLASTNAME=xxx ACADORGANIZATION=xxx INSTALLLEVEL=5 INSTALLDIR=%INSTALLDIR% /qn

Alternative:

MSIEXEC /I %MSIFILE% TRANSFORMS=%MSTFILE% ACAD_SILENT_LICENSE=YES ACADSERIALPREFIX=xxx ACADSERIALNUMBER=xxxxxxxx ACLTFIRSTNAME=xxx ACLTLASTNAME=xxx ACLTORGANIZATION=xxx INSTALLLEVEL=5 INSTALLDIR=%INSTALLDIR% /qn

(difference is in the first/last/org property names - aclt instead of acad)

Notes:

1. MST file isn't necessarry

2. Serial should look like this xxx-xxxxxxxx. Just split it by the comma into prefix and number.

3. INSTALLLEVEL=5 means Complete install (3=Typical, 1=Minimal)

4. INSTALLDIR is a _must_. Without this property set, the Autodesk Licensing Service _will_ cause you trouble when launching AutoCAD.

Thanks a lot. I had taht problem with the license and the solution wasn't on Autodesk website (or at least I didn't looked carefuly enough)

Is it possible to install the AutoCad LT 2006, with no serial key, then when the user run AC it ask for the key and to reg the product? I would like to deploy AC with SMS.
