There was one test way before if you remember with a direct photoshop plug-in. However the reactor is a bit memory hungry and together with a super memory hungry photoshop it was a recipe for disaster (especially that many people are still running 32 bit photoshop due to compatibility with older plugins) so it needed a complete 180 degrees redesign.
There are some nifty tricks in this new iteration, that should solve all those problems. First the Reactor Player doesn't run in the same memory space as Photoshop so there is no memory collision (and for example in case of the Reactor Player crash, it will have no effect on Photoshop), second - and this is a nice one, if you still use 32bit photoshop on 64 bit system, the reactor plugin can run in 64 bit mode directly from 32 bit photoshop giving you benefit of the computer 64bit OS.
Reactor Player doesn't need Photo Reactor to run already created Effect (VFBOX) files, but if you want to edit the VFBOX or create new effect, you will obviously need one. I will supply it with few prepared effects so it can be worthwhile even as standalone plug-in.
Beta Version is here:
http://www.mediachance.com/files/Reacto ... _64_32.exe
This installation is for 64-bit windows and it will install plugins for both 32 bit and 64 bit hosts (like Photoshop)
Install in default location in program files, don't try to install it somewhere inside photoshop. A Deployment wizard will run after that will try to find the hosts and copy the necessary files there.
It was tested on
Photoshop CS2 (32-bit)
Photoshop CS5 (64-bit)
Photoshop CS6 (64-bit)
Corel Painter 2017 (64-bit)
Photo-Brush (you need to go to PB Filters, Manage Plug-ins and add folder C:\Program Files\ReactorPlayer\plugin32\)
The Deployment wizard that launch after install will try to find locations of plugins from registry and from known folders. For software that the deployment wizard didn't find, just go to C:\Program Files\ReactorPlayer\ and there are two folders \plugin64\ and \plugin32\ each with its own 8bf file. For 64 bit application copy the reactor64.8bf and for 32-bit apps reactor32.8bf to their plug-in folder. Don't copy anything else, just the 8bf file.
The plug-in is a bit special because even for 32 bit applications it runs the 64-bit Reactor Player. So for example Photoshop 32 bit or even Photo Brush will all run the 64 bit version of reactor player.

If you still have 32 bit Windows only, at this moment you can't install this. (This will come later as a 32-bit only version, but I would recommend abandon 32 bit windows altogether at this moment

There are just two VFBOX effect supplied as a test at this moment that I borrowed from DAP as I didn't have time to whip something nice. You can import/copy any other VFBOX (for example from DAPPRO5/Reactor/ folder, but don't just copy everything as many effects in DAP are helper effects for masks etc) There is no interface in player to remove the added effects you don't want (yet).
All imported or edited effects in RPlayer are saved in C:\Users\<whateverisyourname>\Documents\ReactorPlugin\Reactor\ so you can directly copy the vfbox files there.
Reactor Player doesn't need to have Reactor installed in order to run those effects, only if you want to create new or edit others.
If you have Photo Reactor you can launch editing mode directly from the plugin - then hit save in Reactor to generate VFBOX in the correct Documents location and refresh the list in player - same way as in DAP.
This is BETA for testing purposes. Things may change.
