Application installation methods vary widely in the DOS world. Some installations involve nothing more than copying the software from diskette to the hard disk. In more complex applications, the install procedure may check the workstation configuration (both hardware and software), implement copy protection and modify system files.
For most DOS applications, installation under OS/2 Version 2.0 is simply a matter of starting a DOS full-screen or windowed session and following the instructions supplied with the package as if the installation was taking place on a DOS system. However, some may not work correctly because of the special requirements of the installation program.
