Solving the AutoCAD Failed Installation, Aborted 1603 error

What is the 1603 Install Error

The 1603 MSI installer error is a generic error code “A fatal error occurred during installation” on Windows 7, Windows 8 or Windows 10. Basically,  it’s not specific; anything could have gone wrong.

Microsoft document this error and lots of possible ways to solve it here…

You receive an “error 1603: A fatal error occurred during installation” error message when you try to install a Windows Installer package

Fix AutoCAD specific 1603 Errors

Aside from the Microsoft documented 1603 errors above, AutoCAD itself has numerous issues with their installer mechanism which when failures occur can also generate the generic 1603 MSI error code.

  6. Once setup has completed…
    1. Make sure to fully close the AutoCAD setup program 
    2. Back in the Converter app, make sure it has completed the final stage of processing using the “Old AutoCAD Program Reviver” tab – it should display “SUCCESS” in green…
    3. Now Reboot your PC
  7. Your AutoCAD 2000i is ready to run! Simply use Windows Explorer, navigate to c:\acad2000i and double click acad.exe (if you want a shortcut on the Desktop you will have to manually create it). 

Installing the AutoCAD 2000i sp2 service pack

  1. download the locked AutoCAD 2000i sp2 from here or download the unlocked AutoCAD 2000i sp2 from here
  2. Next, unzip and save the service pack file to c:\Autodesk\sp – do not install yet

  4. Install the 2000i sp2 by running either the c:\Autodesk\sp\u090_u181p.exe for unlocked or c:\Autodesk\sp\u090_u181p_swl.exe for locked
  5. Once your sp is installed, start the Longbow Converter tool again; we are going to repeat some of the steps from the original installation before. Select the 2nd tab, pick the copy of your AutoCAD 2000i CD on your hard drive which last time was in c:\Autodesk\acad2000i folder, now select the 3rd tab, select the install folder c:\acad2000i now click Fix.

  3. If your AutoCAD crashes while interacting with the Ribbon click here
  4. If you are unable to activate your product, or the activation process crashes:
    1. Try uninstalling the July 2014 Microsoft security update

AutoCAD “There was a problem sending the command to the program”

If you are seeing the message “There was a problem sending the command to the program” when you double click a DWG file from Windows Explorer, then the solution is to follow the instructions listed for your AutoCAD version below:

If you do not see your version of AutoCAD listed, or you are not an AutoCAD user, leave me a comment below and I’ll check it out for you.

AutoCAD running slowly on Windows 10, Windows 7 and Windows 8

If your are running on Windows 10, Windows 7, Windows 8 or Windows 8.1 and your AutoCAD has suddenly started running slowly, or perhaps you are seeing “AutoCAD is not responding” message more than usual, then read on…

Check your installed programs… See if you have “Microsoft WSE 3.0 Runtime” installed, if so, simply uninstall it – it’s been replaced in Windows 7 and Windows 8 with WCF, which is built in.

Verifying License… AutoCAD not responding… Crash!

Windows 10, Windows 7, Windows 8 and Windows 8.1 users (32bit and 64bit) – If you are encountering Autodesk licensing issues such as blank Authorization code (authcode) screens or even crashing on startup with messages like “Verifying license…” then “AutoCAD has stopped responding” when launching AutoCAD, it could be caused by:

  1. The July 2014 Windows Security Update KB2962872
    1. these KB’s may also affect your system too – KB2943357, KB2977629 and KB2976627
  2. You are using a version of Microsoft Internet Explorer which is not compatible with your version of AutoCAD
    1. Try simply installing the latest version of Internet Explorer 11 from here – EIE11_EN-US_MCM_WIN764.EXE

NOTE: If you are primarily seeing script errors, then first check out how to enable scripting support in IE 11

Here is a list of AutoCAD versions (and other similarly labeled Autodesk products too) that most likely will be affected…

  • AutoCAD 2005
  • AutoCAD 2006
  • AutoCAD 2007
  • AutoCAD 2008
  • AutoCAD 2009
  • AutoCAD 2010
  • AutoCAD 2011
  • AutoCAD 2012
  • AutoCAD 2013
  • AutoCAD 2014

Windows Security Update KB2962872

This update can causes all Autodesk products to crash on licensing verification specifically when using these newer versions of Microsoft Internet Explorer

  • Internet Explorer 10
  • Internet Explorer 11

You can very easily uninstall KB2962872 using these short steps:

  1. Open your Windows Control Panel
  2. Navigate to Programs
  3. Click View Updates
  4. Now search for KB2962872, if KB2962872 is listed there, simply select it in the listbox and then click uninstall
  5. Let your machine take a while to think, now reboot.
  6. Now try your Autodesk product again.

If the KB2962872 doesn’t solve the problem, these KB’s may also affect your system – KB2943357, KB2977629 and KB2976627

Apparently, this is no longer relevant –  Another reason is that because you have Microsoft Internet Explorer 11 installed on your system. The solution is to rollback to Microsoft Internet Explorer 10, or maybe back as far as Internet Explorer 8

Failing that, I did find this link on the Autodesk website regarding ‘Script Errors in AutoCAD activation‘ – perhaps it helps  somehow. If that fails, and you haven’t yet tried it – Try simply installing the latest version of Internet Explorer 11 from here – EIE11_EN-US_MCM_WIN764.EXE
