What is PC_DIMMER?
PC_DIMMER is lighting-control software for stage fixtures, not a utility for dimming a laptop screen. It brings LED PARs, moving heads and other lighting devices into a shared control environment. The official project describes support for up to 16 DMX universes, while the publisher lists MIDI, DMX512 and network control alongside chase editors and a party module.
Its hardware-abstraction approach gives different devices a common interface. A terminal interface and web interface provide ways to connect your own applications; the publisher also links a separate Android application. The Windows download here is the EXE setup file linked directly from the official homepage.
The official repository lists Windows 10 and 11 with x86/x64 support, but this does not establish the architecture or version of the current setup file. The publisher still describes version 6 as in development. Do not assume this unversioned installer contains that forthcoming release, or that a particular lighting interface has been verified with it.

Good to know
- The publisher describes version 6 as in development; the linked installer has no confirmed version or release date in the evidence collected.
- Project-level x86/x64 support does not identify the architecture of this exact setup file. Compatibility with a particular lighting interface has not been tested here.
