  4. In the AutoCAD R14 setup program…
    1. navigate through each setup dialog as normal, with these exceptions…
      1. Make sure you do a Typical Install (not a Full Install)
      2. 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)**
  5. Now carry on with the install
    1. Do not reboot once the install is complete
    2. 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.

Troubleshooting

  1. If your AutoCAD R14 setup is not starting after 45 minutes…
    1. First try turning off UAC, rebooting, then restart the steps above.
    2. 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
  2. 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.
  3. 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
  4. 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
  5. Issues with Calcomp Digitizer – Calcomp Digitizer not working
  6. If the setup displays an error message

    InstallError (IUO)

    try unplugging any External USB drives
