AutoCAD LT is a two-dimensional computer-aided drafting and design program. The program is developed by AutoDesk and is provided in 32- and 64-bit versions. AutoCAD LT offers a variety of drafting, collaboration and documentation tools. If you have the 32-bit version of AutoCAD LT installed on a 64-bit operating system such as Windows 7 64-bit or Windows Vista 64-bit, you will still be able to run the program with a few extra steps.

Click the "Start" button and select "All Programs." Find the AutoCAD LT program listing in the program list. It may be listed in the AutoDesk folder. Click the program icon to launch it and see if it can work natively on 64-bit Windows.

Click the "Start" button and select "My Computer" if AutoCAD returns an error when trying to launch. Double-click "C:" and go to "Program Files." Find the AutoDesk folder and double-click it.

Scroll through the list of files to find the ".exe" file that launches AutoCAD LT. Right-click this file and choose "Properties."

Click "Run this program in compatibility mode for:" and select "Windows XP SP2" in the drop-down menu below this option. Click "Apply" and "OK." Launch AutoCAD LT to confirm the compatibility mode fixes the launching problem.
