Here you can download Design Manager installation files

Design Manager 8.11.0.0 works with:
AutoCAD 2000-2018 (32 & 64 bit)
Inventor 2018 (64 bit) (64 bit does NOT work on Windows 8, Windows 10 is OK)

Notes:
1/ Download Design Manager and unzip to a temporary folder then run DmMaster.Exe
2/ Release Codes are required to run these applications.
3/ The OLE Object setting for AutoCAD 2018 should be AutoCAD.Application if this does not work use AutoCAD.Application.22
4/ Application Caption setting for R18 is AutoCAD 2018
5/ For full functionality Design Manager requires the AutoCAD VBA enabler to be installed for the version of AutoCAD in use..
6/ If using Windows 7 or 10 we advise you to run Design Manager and AutoCAD/Inventor as Administrator, you can make this setting in the Windows properties for the application under the Compatibility tab. Also turn off UAC.
7/ If the database files are on a Windows server make sure users have EXPLICIT ‘Full Control’ rights over the folder
Membership of a group with rights is not sufficient due to an anomaly with Windows Server and .DBF files.
