How to install DrafixCAD

A quick word of advice: best to follow the instructions below precisely and to the letter, including folder names and paths, that way you will reduce the risk of having any problems…

  1. Obtain your copy of the Longbow Reviver tool here – you need version 4.10 or newer
  2. Copy your entire Drafix CAD CD to a folder on your hard drive, say C:\DrafixCAD\CD
  3. Start the Longbow Reviver tool
    1. Select the 1st tab named “Old Installer Reviver
    2. Next, select the path the folder where you copied the CD to = should be C:\DrafixCAD\CD
    3. Next, hit the ‘Fix Old Installer‘ button and follow the onscreen instructions
    4. Once you have clicked the final OK button the Reviver will force the setup.exe to start up. Be patient – it may take up to 90 minutes to start, so go and make some coffee!
  4. When the DrafixCAD setup appears
    1. If setup asks you if you want “Network”, if possible say No – selecting Network will give a “Can’t Open Library” error on first launch.
    2. Install as normal except make sure you **don’t** install to C:\Program Files (x86)\Softdesk\CAD, instead, install to C:\Softdesk\CAD 
      Select a different folder

      Be sure to select a different folder c:\Softdesk\cad



    3. Also, don’t reboot if prompted to do so
  5. Once DrafixCAD is installed and before running the application…
    1. Go back to the Reviver tool
    2. select the 2rd tab named “Old Program Reviver
    3. Using the ‘…’ button select the path C:\Softdesk\CAD
    4. then click the ‘Fix Old Program‘ button.
  6. Now you can happily run your DrafixCAD!

  1. Your Program “Installing DrafixCAD on Windows 7, Windows 8 and Windows 10 64bit” will not install on my Windows 8.1 PC.

    • Message for Delbert Massey
      Were you ultimately successful in getting Drafix Cad to run on your Win 8.1 machine?
      I have a large number of legacy Drafix Cad files I wish to open and convert to DWG files for use in alternate cad software.
      I’m seeking a copy of Drafix Cad Professional V 4.1 to facilitate running under WIN10 64bit after Longbow Reviver installation.
      Any help much appreciated

  2. Does Installing DrafixCAD on 64 bit is little bit confusing rather than on 16 bit windows.operating systems , May be better to continue to use 16 bit windows. Majority of Drafting software work on 1 bit Windows versions

    • People want to run on the latest Windows Operating systems so that they utilize the latest hardware and are secure from hackers. Windows 10 64bit is what they want to run on. This post allows them to do that

  3. Drafix Problem.

    I purchased the reviver home addition for myself and installed Drafix Cad 4.0 for windows 95 on a windows 10 pro machine -NO PROBLEMS.

    I pruchased another Reviver for a friend and cannot get it to run on a new WIndows 10 Home machine.

    It goes through the installation ok but will not run because of missing cadagent.dll that I can see in the folder on my pro machine that works but on on the one that doesn’t work.

    Both use the exact same drafix source file.
