The following specifications are enough to run the 32-bit version for legacy systems. The regular 32-bit and 64-bit versions require a machine that matches the recommended specs.
Windows 98 or newer (KernelEx is required on Windows 98 / Me)
Pentium 1 or a better x86-compatible CPU
Display resolution: 800x600
Some kind of sound device
15 MB of free disk space
Recommended specs

To fully enjoy OpenMPT, you will probably want at least a machine like this one:
Windows 7 or newer
An x86-compatible CPU with the SSE2 instruction set, 1+ GHz and two or more cores
A large display :-)
A sound device with native low-latency ASIO support
A big hard disk for many modules and samples
Bear in mind that VST plugins often come with their own system requirements and that you will probably need a much more powerful rig to run some of them.
Wine
If you are running Linux or a similar Operating System, you can run OpenMPT through Wine. The software runs fairly well with the exception of a few little glitches. It might help to get wineasio as well.
