Can't "Open With... Incopy.exe" in InCopy CC 2014 for Windows

Question

To say I'm frustrated would be being kind to Adobe... I'm really going to try to suppress my sarcasm and criticism at how incompetent Adobe programmers and program managers must be to allow this kind of problem to exist...
I have some InDesign documents (.indd) that I want to right click on and set InCopy as the default program. After some trial and error, on two systems, I was able to adjust the registry to get this working.  On the third, so far, I've tried:
1. Reinstalling Incopy - Did not work
2. Copied the InCopy.exe to WWXXYYZZ.EXE - and while this allows InCopy to appear in the list of "other programs", it won't open. So...
3. I searched the registry for WWXXYYZZ.EXE and replaced all instances with InCopy.exe (Why I copied it to this weird name in the first place - easier searching of the registry - this didn't work.
4. Edited the following registry locations to ensure they pointed to InCopy.exe - but every time I change it to this exe, Windows won't open.  I'm sure Adobe would like to blame Microsoft for this, but when EVERY SINGLE OTHER Executable (and even the renamed copy) CAN be assigned to open it using the "Open with" dialog, I'm left believing that Adobe programmers decided not to do something properly in registering the exe with the registry - or registered it in such a way so as to prohibit it from being displayed in that menu for some reason.  SO HOW DO I FIX THIS!?!?!?!
Registry locations edited (reset to point to InCopy.exe):
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.indd\OpenW ithList]
"a"="InCopy.exe"
"MRUList"="a"
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.indd\UserC hoice]

"MRUList"="a"
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.indd\OpenW ithProgids]
"InDesign.Document"=hex(0):
I'll repeat - HOW DO I FIX INCOPY TO OPEN AN INDESIGN DOCUMENT BY SIMPLY DOUBLE CLICKING? (and yes, I do have to shout that!)

Answer 1

No thanks to the utterly useless folks at adobe, I got this working - I found a registry key that had the previous version of InCopy and once I deleted that, I could now right click and "Open With" InCopy and permanently assign it.
