1. Obtain your copy of the Longbow Converter here
2. If you have CDs:
   1. Using Windows Explorer, copy Disk 1 of your Civil 3D CD to your hard drive, to a folder path c:\Autodesk\Civil3d2009
   2. Next, copy Disk 2 of your Civil 3D CD directly over the top of Disk 1, overwrite all files in your previously copied c:\Autodesk\Civil3d2009 folder
   3. Same again for Disk 3
3. If you have a single self extracting exe downloaded from Autodesk
   1. Run the exe, it will ask to unzip to a folder inside of c:\Autodesk, make a note of the folder for later use (we’ll refer to it from here as c:\Autodesk\Civil3d2009), now click OK. Wait until all of the files have extracted, when they do, the Civil 3D 2009 setup will automatically launch – simply close it and move to the next step.
4. Now, start the Longbow Converter tool
   1. Select the 1st tab titled “AutoCAD 32bit Installer Converter“
   2. Using the ‘…’ button, select the c:\Autodesk\Civil3d2009 folder and click OK
   3. Once you have c:\Autodesk\Civil3d2009 selected , click the “Convert…” button to convert the media.
5. Once the conversion process is complete, click Install/Run Setup to start setup. Simply install as normal.
6. Windows 8, Windows 8.1 and Windows 10 users: Once the installation process is complete, go back to the Converter, select the 3rd tab, pick the newly installed C:\Program Files (x86)\AutoCAD Civil3d 2009 folder, then click “Fix Old Program…“.
7. Now you can happily run your Civil 3D 2009 32bit on Windows 10, Windows 7 and Windows 8 64bit.
