Installing your AutoCAD R14 on Windows 7, Windows 8, Windows 8.1 or Windows 10 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.

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 Converter here
  2. Before starting, we recommend turning off Windows UAC before installing AutoCAD R14
  3. Using Windows Explorer, copy your entire AutoCAD R14 CD to your hard drive, to a folder path c:\Autodesk\R14CD
  4. Start the Longbow Converter application…
    1. Select the 2nd tab named “Old AutoCAD Installer Reviver
    2. Using the “…” button, pick the c:\Autodesk\R14CD folder path (where you copied your R14 CD to in step 2)

      Selecting the your copied R14 CD in the Converter tool

    3. Next, click the “Run Old Installer” button.
      1. Read and understand all the prompts before pressing OK.
      2. Now, I know it’s unheard of these days, but at this point expect to wait up to 45 minutes for your AutoCAD R14 setup.exe program to appear
    4. Once the setup starts, stop and read the next steps all the way to the end!
    5. If your AutoCAD R14 setup does not start after 45 minutes, read the Troubleshooting section below.
  5. In the AutoCAD R14 setup program…
    1. navigate through each setup dialog as normal, except when you get to the installation folder input dialog, **it’s vitally important to make sure you install to c:\acadR14 (not .\AutoCAD R14 as usually prompted)**
  6. Now carry on with the install (do not reboot once the install is complete).
    1. Ignore any errors related to not being able to create the shortcut e.g. “Cannot Create folder ‘AutoCAD R14’“, you will have to create a shortcut on your computer Desktop to your c:\acadR14\acad.exe by hand.
    2. Do not reboot if prompted to do so
  7. Once your AutoCAD R14 setup has completed the installation…
    1. Go back to the Converter tool
    2. select the 3rd tab named “Old AutoCAD Program Reviver
    3. Using the “…” button, pick the newly installed c:\acadR14 folder
    4. Next click the “Fix Old Program” button.

  8. Now you can happily run your AutoCAD R14 on Windows 7, Windows 8, Windows 8.1 or Windows 10 32bit or 64bit
    1. Using Windows Explorer, navigate to c:\acadR14 and double click acad.exe
  • If your AutoCAD R14 setup is not starting after 45 minutes…
    • First try turning off UAC, rebooting, then restart the steps above.
    • If it is still failing, most likely it’s because of another application on your system which is preventing our setup routine from starting (perhaps anti-virus, or similar) – try installing R14 from Windows Safe Mode
  • If you are getting either a Bad Mem Pointer error and or a Smartheap handler recursively re-entered error when you start your AutoCAD R14 then you need to re-run all the steps above, taking care to do each step precisely as it says, most likely you are missing from step 5 or you have not installed to c:\acadR14 as stated in step (7) above.
  • When starting AutoCAD, if you receive an ‘acad.exe – System Error’ message: The program can’t start because ac1st15.dll is missing from your computer. Try reinstalling the program to fix this problem. If you carried out step (7) above, then try rebooting your PC
  • If you are getting a WinHelp() error when pressing F1 to try and access the Help system then simply install the WinHelp (WinHlp32.exe) module from Microsoft

  • If you have crashing problems using the File->Open or File->Save dialogs inside of AutoCAD please read this blog entry on the File->Open or File->Save Crash in AutoCAD

  1. Purchased and downloaded the Converter software to use for AutoCAD R14 and it works without a hitch on new Dell laptop running Windows 8.1. Also it is much faster and more responsive.

  2. Howdy, Longbow folks.

    Using your Converter, I was able to install AcadR14 on my Windows 7 (32-bit) PC, apparently without problems, following the instructions from you: http://www/ and .
    From the remarks in your blog site, I should have expected to wait up to 45 minutes before the Setup.exe should appear; however on my end, I didn’t have to wait at all. Setup.exe appeared after a few minutes, I ran it and AutoCAD was installed on my Windows 7 PC and seemingly works. The only glitz I experience now is when trying to running Render (a .ARX extension file), I get an error, “_render Unknown command “RENDER” Press F1 for help”. After installing the WinHlp32.exe for Windows 7 from MS so I open the AcadR14 Help menu, I found that “Help” doesn’t offer useful insight. The same installation of AcadR14 on my laptop (running XP Pro) works perfectly and Render runs.
    I am guessing that when I installed the Converter, I might have skipped a step, which might explain why the installation was so quick. Should I re-install the Converter carefully or is there a problem with .ARX files?

    Thanks, Charles.

    • Yes, make sure you have the latest Converter App, then uninstall and reinstall – it should work just fine for Render. Help is discontinued by Microsoft on Windows 10. Only Windows 7 and Windows 8 (and 8.1) support the old WinHlp32 framework.

  3. Hi, Loading onto Windows 10, once the installer runs (Step 6) it prompts x2 blank error messages, OK these to carry on, the third error message is causing a process abort.
    At 82% complete it displays
    Error: -6 File:C:\Autodesk\R14CD\Autocad.R14\DATA\rtextur.z
    after OK to this error message the installer aborts the process, removes what was written to C:\acadR14 so the Old Program Reviver has nothing to work with.
    Any suggestions?
