My OS is Windows 7 Ultimate 64-bit and Windows 8 Pro 64-bit (I'm trying it on both my laptop and desktop).

Making progress! 
Your Windows machines look fine to me, and they are peppy dual-core processors, which is great, and for 32-bit mode they have enough memory . . .
[
NOTE: Since the Acer Aspire 7739G notebook has an Intel i5 dual-core processor, it should have the same or similar onboard audio as the Mac Pro here in the sound isolation studio, which works very nicely . . . ]
At this point, there are two tests that will be helpful:
(1) NOTION 3 as ReWire host controller and Reason 6.5 as ReWire slave (1.1) Close all apps and reboot the computer . . .

NOTE: When you are making sense of ReWire and doing experiments, it tends to be a good idea to reboot more frequently, and this also is the case on the Mac, where at time I did a cold reboot (complete power down and reboot) every 15 minutes or so, which included doing a cold reboot of the MOTU 828mkII external digital audio interface. And this is important, because as I explained somewhere, when everything is not configured correctly, this can result in what one might call "ghost" or "phantom" processes, DLLs, threads, UNIX daemons, or whatever, and the only way to clear the lingering stuff is to do a cold reboot . . . ]
(1.2) Start NOTION 3 and toggle the "Enable ReWire" option . . .
(1.3) With only NOTION 3 running, switch to the NOTION 3 Mixer and then click on the tiny "+" sign on the right of the "ReWire" button at the top of the NOTION 3 Mixer in what I suppose is the "banner" section or whatever, which will look similar to the following screen capture from the Mac version, where the "ReWire" button and its "+" sign are at the far-right of this image . . .

(1.4) When you click on the "+" sign and hold the mouse, you should see Reason 6.5 listed with a fly-out triangle, which is what you will use to get the full list of Reason channels, where you will select "Channels 1-2", which will be the Master stereo output of Reason 6.5 . . .
This creates an Auxiliary ReWire Channel in the NOTION 3 Mixer, and it will receive the audio generated by Reason 6.5 . . .
(1.5) In your NOTION 3 score, add a Piano and then add a bunch of empty measures, which should be enough to map to a minute or two, and Save the NOTION 3 project . . .
(1.6) Now you can start the 32-bit version of Reason 6.5 and open one of the DEMO songs . . .
(1.7) Switch to NOTION 3 and press the "Play" button, and you should see both the NOTION 3 and Reason 6.5 transports moving, and you should hear the Reason 6.5 DEMO song, where if you look at the NOTION 3 Mixer, the Auxiliary ReWire Channel should have LED or level activity . . .
(1.8) You might pause the song for a moment and add some Piano notes on the Piano staff in NOTION 3, where if you rewind the NOTION 3 transport and press Play, you will have the Piano notes and the audio from the Reason 6.5 song . . .
(1.9) Save the NOTION 3 project; quit Reason 6.5; and then quit NOTION 3 . . .
EXPECTED RESULT: You will be able to create the Auxiliary ReWire Channel in the NOTION 3 Mixer, and you will hear Reason 6.5 audio for the DEMO song you selected. And you can add Piano notes to the NOTION 3 score, and they will be played and heard, as well . . .
(2) Cubase 5 as ReWire host controller and NOTION 3 as ReWire slaveIf the first test is successful, then I think you can do the second test, and it also will work, but if not, then it is important to ensure that you specify the output of at least one channel in the NOTION 3 Mixer as a ReWire channel pair, which for NOTION 3 acting as ReWire slave is done in the drop-down list at the bottom of the NOTION 3 Mixer for each track, where you can begin by setting the Output for the NOTION 3 Master stereo track to "Channels 1-2", which is the ReWire channel pair you will use to represent NOTION 3 in Cubase 5 . . .
The following image shows a NOTION 3 Master stereo track with its output set to "Channels 1-2" as it appears on the Mac, which will be similar to the way it looks in Windows . . .
NOTION 3 Master Stereo Track ~ Output Set to ReWire Channels 1-2 ("Ch 1-2") You can refer to the Propellerhead Software instructions for doing ReWire with Cubase 4, and these instructions might provide a few clues . . .
THOUGHTSGetting everything configured correctly takes a while the first time, and for reference it took me approximately three weeks to make sense of ReWire on the Mac, during which time I was not a happy camper, which is an understatement, but I kept doing experiments and reading about ReWIre, and eventually it made sense, where the key is that there is a bunch of stuff that needs to be configured very precisely, and there certainly is more to getting everything correctly configured than one might infer from the typically sparse user documentation on how to do ReWire . . .
[
NOTE: Once you get ReWire working nicely, you will be able to tell someone with the same computers, version s of WIndows, and the same digital music production applications how to do ReWire in perhaps 5 or so minutes, but discovering how to do it is not so easy, where if some of the difficulty is a matter of ReWIre being a new technology, so while you are doing tests and trying different configurations, parameters, and settings, you also are learning what ReWire is and how it works, and while the ReWire documentation at the Propellerhead Software Support website is more detailed, it is not so current with respect to versions of various Digital Audio Workstation (DAW) applications, where as an example its instructions for Cubase cover version 4, but the current version of Cubase at present actually is 6.5, which is the reason that I generally consider the overall user documentation on ReWire to be on par with the "Beavis and Butt-head" version: "ReWIre rocks, and smart people like use it or something. Uhhhhhh, thank you, and please drive through" . . .

The test with Cubase 5 and Reason 6.5, where everything is 32-bits, is important because it verifies that Cubase 5 does ReWire on playback with Reason 6.5, which verifies the ReWire infrastructure and so forth for Cubase 5 and Reason 6.5 in 32-bit mode . . .
The first test with NOTION 3 (see above) covers the case where NOTION 3 is the ReWire host controller, and Reason 6.5 is the ReWire slave, which also needs to work, since it is an important step . . .
The second test with NOTION 3, where Cubase 5 is the ReWire host controller and NOTION 3 is the ReWire slave is the key test, and it needs to work, as well . . .
The way I recommend doing it is incremental and stepwise, where you begin by getting it to work with Reason 6.5 and then move forward, which is a logical way to do it and will reveal any configuration problems along the way . . .
You are making progress, which is very important, so keep at it, and report the results of the first test (see ablve) where NOTION 3 is the ReWire host controller and Reason 6.5 is the ReWire slave, all of it being 32-bit mode, of course . . .
Lots of FUN! 
P. S. And you might consider doing the experiment regarding copying "REWIRE.DLL" to the "SYSWOW64" folder as
DennisAnderson explained his recent post, but be certain to have a way to undo it, and only do it if there is no "REWIRE.DLL" file already in the "SYSWOW64" folder . . .
