Windows 95/98/NT/2000

DrScheme runs under Windows 95/98/NT/2000. DrScheme does not run with earlier versions of Windows, such as Windows 3.1 (even with the Win32s extension).

The Windows version of DrScheme is distributed in the installer program plt.exe. (The floppy-disk distribution consists of plt.exe on disk 1, plt.w02 on disk 2, etc.) Running the installer unpacks the DrScheme files to your hard drive, usually in a subdirectory named plt within your main Program Files directory, and sets up shortcuts for the DrScheme programs under the Start menu.

The installer also creates uninstall.exe in the installed plt directory. Run uninstall.exe to uninstall DrScheme before installing a new version. Old versions of the uninstaller (before version 100) are not able to remove all the files, so you must manually delete the old plt directory after running uninstall.exe.

After installing DrScheme, run it via the Start menu by selecting Start Programs PLT Scheme DrScheme. The Start menu also contains DrScheme Jr in the same place.
