During Enthought Canopy install, canopy.exe fails to run to setup environment on Windows 7 - enthought

Question

I have a 64bit Win 7, installed the 64 bit canopy.
The first part installs fine, but if I try to launch canopy to set up the environment from the start menu (or from the desktop icon or "C:\Program Files\Enthought\Canopy\App\Canopy.exe" which is where they point) absolutely nothing happens.
This seems to be the same problem that has been reported a few times before:
Canopy Does not Start on Windows 7 despite successful installation
Install 32 bit Canopy on Win 7, 32-bit machine fails
Enthought canopy not running
but none of these questions have been resolved. What they all have in common is that they relate to Windows 7.
These questions are followed up by a request for the log:
"C:\Users\\AppData\Roaming\Enthought\Canopy\log\"
However there are no logs, there isn't even a
C:\Users\\AppData\Roaming\Enthought directory.
However I have found that if I go into:
C:\Program Files\Enthought\Canopy\App\appdata\canopy-1.1.0.1371.win-x86_64
and run the copy of Canopy.exe in there it allows me to setup the environment and run canopy from within this subdirectory (the desktop and start menu links still fail) . This also creates the
C:\Users\\AppData\Roaming\Enthought directory and logs.
BUT I am worried if I do this I will cause problems for myself further down the line. Can someone tell me why the canopy.exe linked to in my start menu isn't working?
I do have a previous installation of WinPython 2.7 in
C:\Python27\WinPython-64bit-2.7.5.3
thanks
Susie

Answer 1

Existing PYTHONHOME and/or PYTHONPATH environment variables may be interfering with Canopy startup. For details, please see:

Answer 2

Thanks for the report and pointers, Susie. No, you have not created any problem for yourself.
To help us get to the bottom of this, could you be so kind as to answer these questions?:
1) What is the full Target of the non-working shortcut? (Right Click / Properties / Shortcut tab / Target)
2) Can you start Canopy by running this?:
C:\Program Files\Enthought\Canopy\App\Canopy.exe
3) In the light of your previous Python installation, what go you see if you type “PATH” at a command prompt?

Answer 3

1) What is the full Target of the non-working shortcut? (Right Click / Properties / Shortcut tab / Target)
The non-working shortcut target is the filepath you give below:
C:\Program Files\Enthought\Canopy\App\Canopy.exe
2) Can you start Canopy by running this?:
C:\Program Files\Enthought\Canopy\App\Canopy.exe
No. I get about a half second of the spinning 'working' icon on my mouse pointer then stops.
If I run it from the command line it skips straight back out to the next line.
3) In the light of your previous Python installation, what go you see if you type “PATH” at a command prompt?
