UPDATE March 20, 2014: N-Trig today released 64-bit version of its Wintab driver. See this post for details.

I guessed correctly that behind Sony's cryptically named SOAOTH-P0092513-1082.EXE is an N-Trig supplied driver that doesn't discriminate by manufacturer.
Using Universal Extractor 1.6.1 from LegRoom, I opened up the executable and found it contains a much friendlier installer named WinTab_Setup_x32.exe.
I ran the extracted installer on my Acer, rebooted and (voila!) pressure sensitivity is available in 32-bit Photoshop CC.
Don't you love it when stuff just works?
If you have another N-Trig equipped device, give the installer a try and let me know in the comments section below if it works for you!
