Installing AutoCAD Mechanical (MDT) 2006 on Windows 10, Windows 7, Windows 8 or Windows 8.1 32bit or 64bit can be very easily defined in these short steps…

NOTE: These steps do not bypass normal Autodesk licensing/authorization, you should expect to use your own serial numbers in the normal way.

1. Obtain your copy of the Longbow Converter here
2. Using Windows Explorer, copy your entire MDT 2006 CD to your hard drive, to a folder path c:\Autodesk\mdt2006 
3. Start the Longbow Converter tool, select the 2nd tab “Old AutoCAD Installer Reviver“, pick the c:\Autodesk\mdt2006 folder, and click Run. Read and understand all the prompts before pressing OK. Once the setup starts, stop and read the next step…
4. In the setup program, navigate through each setup dialog as normal, except when you get to the installation folder, **it’s vitally important to make sure you install to c:\mdt2006 (not Program Files (x86)\AutoCAD Mechanical 2006 as usually prompted by default)**
5. Once installed, go back to the Converter tool, select the 3rd tab “Old AutoCAD Program Reviver“, pick the newly installed c:\mdt2006 folder and click Fix.
6. Now you can happily run your MDT 2006 on Windows 10, Windows 7 and Windows 8.
