Installation simply involves downloading and unzipping the correct file, then copying the plugin file/bundle into the correct folder/directory for your system. Depending on your DAW or host software, you may then need to "rescan" your plugin folder. The folders/directories suggested below are the defaults for most systems, but you may have a different preferred location.

Mac OS "RUN_ME_FIRST" command file
On Mac OS, you must run the RUN_ME_FIRST.command file before copying any of the plugin files to their destinations. You may need to open System Preferences -> Security & Privacy -> General, in order to allow this command to run.

The RUN_ME_FIRST.command is a simple shell script that removes the "quarantine" attribute from the plugin files. It does not change any of your system settings. Should you wish to, you can examine the contents of the RUN_ME_FIRST.command file to see what it does, by opening it in the TextEdit app.

Other formats

Linux VST3: A linux x64 VST3 version has been made available for testing. Please email me (see contact section below) if you would like to try it. An official linux release will be coming soon.
Apple M1: Fircomp 2 is now distributed as a "universal binary" which contains native code for both the M1 and Intel CPUs. They share the same codebase, however the Intel version has received much more testing so far, and I intend to do much more thorough testing once I have direct access to an M1 mac myself.
AAX: Although I hope to support this format one day, there is currently no planned date to release an AAX version of Fircomp 2.
32-bit VST3, 32-bit AU2, 64/32 bit VST2: There are no plans for Fircomp 2 to support these formats.
