If you are getting the "16 Bit MS-DOS Subsystem" Error Message When You Install or Run a Program see Microsoft's KB Article for WindowsXP or Window2000
Also, I have created the following quick fixes to resolve the issue in another way if the above articles didn't help or if you want to try a more practical and common solution first.
~ Download and run the attached files (Fix16bit.exe and Command.exe) from anywhere on the local machine.
~ Once done reboot the system.
