Rolling back to IE 10 from IE 11 in Windows 7, Windows 8 and Windows 8.1

If you are encountering licensing issues, blank screens or even crashing when launching AutoCAD it could be because you are using a version of Microsoft Internet Explorer which is not compatible with your version of AutoCAD… (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 that most likely will be affected…

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

It could be 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. Here’s how:

 

Windows 7 users

  1. Click Start then Control Panel
  2. Once in Control Panel select Programs
  3. From Programs click Turn Windows Features on or off
  4. Once in the Windows Features dialog, simply un-check Internet Explorer 11 and click OK. You will be asked to reboot, which you should do. Once you reboot, IE 11 will have been rolled back to IE 10
  5. NOTE: If you are still having problems, you can repeat the process from (1) to (4) again in order to downgrade from IE 10 to IE 9 to IE 8. Autodesk products usually do not need further downgrading than IE 8, so if you are still having issues even with IE 8 then it’s most likely something else wrong on your system.
  6. NOTE: If you cannot downgrade far enough, your only option is to upgrade to 7.24  (or newer) of the Longbow Converter tool which now supports Internet Explorer 7 emulation mode

Windows 8 users

  1. Move your mouse to the bottom left corner of the screen, then right click your mouse and select Control Panel
  2. Once in Control Panel select Programs
  3. From Programs click Turn Windows Features on or off
  4. Once in the Windows Features dialog, simply un-check Internet Explorer 11 and click OK. You will be asked to reboot, which you should do. Once you reboot, IE 11 will have been rolled back to IE 10
  5. NOTE: If you are still having problems, you can repeat the process from (1) to (4) again in order to downgrade from IE 10 to IE 9 to IE 8. Autodesk products usually do not need further downgrading than IE 8, so if you are still having issues even with IE8 then it’s most likely something else wrong on your system.
  6. NOTE: If you cannot downgrade far enough, your only option is to upgrade to 7.24  (or newer) of the Longbow Converter tool which now supports Internet Explorer 7 emulation mode.

Windows 8.1 users

Window 8.1 comes with Internet Explorer 11 pre-installed and cannot be rolled back. Your only option is to upgrade to 7.24 (or newer) of the Longbow Converter tool which now supports Internet Explorer 7 emulation mode.

Resolving The Longbow Converter “Error Code 2”

If you are getting an “Error Code: 2” message when converting your 32bit AutoCAD 2008 or newer, then here’s what you need to do…

 

The “Error Code: 2” message indicates that either the Converter was unable to write to the folder (most likely) or that the media was not copied in full (least likely).

  1. In the 1st tab of the Converter tool, you would have selected a path to your 32bit AutoCAD, let’s say for example it is c:\Autodesk\AutoCAD2013
  2. Start Windows Explorer, right click the c:\Autodesk\AutoCAD2013 folder and click Properties
  3. Now un-check Read-Only then click Apply, then Apply to All Files and Folders
  4. Now try again…

If you are still getting the “Error Code: 2” message, then find your specific AutoCAD version from here (on the left side), then use those instructions specifically to install your AutoCAD.

AutoCAD 32bit/64bit side-by-side installation compatibility chart

This blog has been written to help advise those who require 32bit versions of AutoCAD to reside on the same computer system as 64bit versions of AutoCAD.

Before we start, when installing 32bit AutoCAD on 64bit Windows, you should take care not to mix the same version/series of AutoCAD 32bit with the same version/series of the corresponding 64bit version of AutoCAD, on the same computer. The reason is that they were not designed to run in a side-by-side configuration and therefore may conflict. The same rule can generally be made for all Autodesk products.

NOTES:

  • When installing 32bit AutoCAD, we advise that you uninstall all previous versions of 64bit AutoCAD before installing your 32bit version of AutoCAD.
  • If you are installing multiple versions of AutoCAD, you should always install in chronological order, in other words, oldest to newest.
    • e.g AutoCAD 2004, Architecture 2004, Map 2005, AutoCAD 2007, Civil3d 2015
    • Failure to follow this simple rule can render you with missing entry point errors, un-explained crashing, un-installable Autodesk software and more.
  • For best results, we recommend that you install only 32bit versions of AutoCAD on your computer system, however, mixing is possible with care – refer to the chart below if you must have the 64bit version installed on the same computer.

This chart shows which 32bit AutoCAD versions can be installed on the same system as 64bit AutoCAD versions…

  • Green means Should be OK
  • Red/Dark Red means Problems will occur, you should not do this
