32-Bit AutoCAD on a 64-Bit OS

A lot of people are upgrading to Windows 7 these days. I made the move a couple of months ago and I’ve actually enjoyed the new OS– though somehow I still can’t use a ribbon created by anyone other than Autodesk. At the same time, there’s a big push to upgrade to 64bit machines. The problem is that not everyone who’s ready for a new machine is ready to upgrade their Autodesk products. For instance, I’ve gotten quite a few calls about  installing Land Desktop on a 64bit machine. Try to install and you get:

The solution in this case is fairly well known, but I wanted to share it with our readers because it’s so simple and helpful. What you need to do is copy the content of your installation disc to your hard drive. Then open the Setup.ini file, located in the recently copied installation folder,  using notepad.

Near the top of the file you’ll notice two paths, X86_IMAGE_PATH and X64_IMAGE_PATH. When the installer recognizes your 64bit OS it uses the x64 path and says you can’t install. If you change the value to the right of the equals sign to x86, you’ll be able to install. Just save the Setup.ini file and run Setup.exe.

    1. Hi Ramkumar. You can try deleting the line in the setup.ini that says “PLATFORM=NO_WOW_64_PROCESS”. You may also need to use an .msi editor like Orca to delete any actions that include “CheckFor64BitOS”.

  3. This causes Auto desk Design Review 2010 to be installed. But installing AutoCAD 2010 stI’ll gives the same.error.message l. Kindly help

  4. Installing a 14 year old version of a 32 bit application in Windows 10 Pro x64 is going to run but not without problems. The Windows environment for this 14 year old application has changed tremendously and the application is going to show you all its limitations. One of the first limitations is you will find out is that 2004 AutoCAD cannot work with file sizes larger than 25mb. Another problem is that 2004 AutoCAD has problems plotting to x64 printer drivers if you have multiple plotters installed. The x86 emulator in Windows 10 Pro is forgiving but only to a point. It is time to get a newer version of this application and let 2004 AutoCAD die…
