What is pcalua.exe?

Part of Program Compatibility Assistant by Microsoft

What is it?

The Program Compatibility Wizard prompts you to test your program in different modes (environments) and with various settings.
Description of pcalua.exe from Microsoft
For example, if the program was originally designed to run on Microsoft Windows 95, set the Compatibility Mode to Windows 95, and then try to run your program again. If the program runs, the program will start in that mode every time. You can also try different settings. For example, you can test with a 256-color display and a screen resolution of 640 pixels by 480 pixels. Most programs run correctly on Windows XP except for some older games and other programs that were written specifically for an earlier version of Windows. If you are experiencing problems with a program that worked correctly on an earlier version of Windows, the Program Compatibility Wizard helps you select and test compatibility settings that may fix those problems. If a program does not work as expected, run the program in one of the compatibility environments.
