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 2011 CD to your hard drive, to a folder path c:\Autodesk\Civil3d2011
   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\Civil3d2011 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\Civil3d2011), now click OK. Wait until all of the files have extracted, when they do, the Civil 3D 2011 setup will automatically launch – simply close it and move to the next step.
4. Now, start the Longbow Converter tool, select the 1st tab, pick the c:\Autodesk\Civil3d2011 folder, and click the Convert button.
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 2011 folder, then click Fix.
7. Now you can happily run your Civil 3D 2011 32bit on Windows 10, Windows 7 and Windows 8 64bit.
