12.18.1 Runtime library requirement on Windows

LispWorks for Windows requires the Microsoft Visual Studio runtime library msvcr80.dll . The LispWorks installer installs this DLL if it is not present.

Applications that you build with LispWorks for Windows also require this DLL, so you must ensure it is available on target machines. It is part of Windows Vista, but for earlier Windows operating systems you should use the Microsoft redistributable mentioned below.

At the time of writing, the redistributable vcredist_x86.exe for use with for LispWorks (32-bit) applications is freely available at

The redistributable vcredist_x64.exe for use with LispWorks (64-bit) applications is freely available at

Run the redistributable from your application's installer, or tell your users to run it directly themselves before running your application.

Note that Windows Installer 3.0 or later is also needed on the target machine for Windows 2000 or XP.
