Launching custom HTML5 UI's in Photoshop CC 2014 (15.2)

Question

Problem:
I am trying to get Photoshop CC to launch custom built HTML5 UI’s.  In doing so I have hit a few roadblocks:
Roadblocks:
• The documentation online to install and launch HTML5 UI’s from scratch is out-of-date:
http://www.adobe.com/devnet/creativesuite/articles/a-short-guide-to-HTML5-extensions.html
• The supported method, using Adobe Extension Manager CC requires an internet connection, which our network does not (and will not) ever have.
• The workaround instructions to use a request code from an internet-capable workstation are incomplete

What I think I need:
Right now I am blocked from using HTML5 UI’s.  If a rep from adobe could tell me where on my workstation to place unsigned extensions that would be a great first step, and then if they could verify that the registry work-around is still supported with Photoshop CC 2014 (15.2) that would probably unblock me.

No, just keep it at sRGB. As long as you have the "preserve" policy, the working space actually isn't all that important. The embedded document profile will always override it (as it should).
I had to read this a couple of times to follow the trail properly. Leaving Perfect Effects (which I don't know at all) out of it - does the very same file iteration, with the same edits, look different between Photoshop and Lightroom? Did I get that right?
In that case you have a bad monitor profile. This can sometimes throw off one application but not the other. Recalibrate, or if you don't have a calibrator go into Windows color management and set sRGB IEC61966-2.1 as default display profile. When done relaunch all applications so that they can pick up the new profile at startup.
