Can't Open .ep File in Windows 7 (64 bit)

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Double click an .ep file.
2. Pencil opens but shows an Untitled Page instead of the selected file.

What is the expected output? What do you see instead?
The file should open.

What version of the product are you using? On what operating system?
1.3.4

Please provide any additional information below.
I associated the file type (.ep) with Pencil but it didn't work.  I can use the 
menu (Pencil > Document > Open) to open the file.

Windows 7 Professional 64-Bit

Have the same issue on Mac OS X 10.6.8 with a stand-alone version. Strangely 
enough it works for me, if I open a file from within Pencil itself 
(File->Document->Open).

Just tried again after installing 2.0.2 and it still doesn't work.  Using stand 
alone install.

I had to change the file association from pencil.exe to:
"C:\Program Files (x86)\Evolus\Pencil\xulrunner\xulrunner.exe" "C:\Program 
Files (x86)\Evolus\Pencil\app\application.ini" "%1"

To fix problem:
1. Open .ep file in explorer with "Open with" -> "pencil.exe"
2. Apply this windows registry update:
------------------
Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\Applications\pencil.exe\shell\open\command]
@="\"C:\\Program Files (x86)\\Evolus\\Pencil\\xulrunner\\xulrunner.exe\" 
\"C:\\Program Files (x86)\\Evolus\\Pencil\\app\\application.ini\" \"%1\""

Solutions in posts #5 and #6 doesn't works for me. Even when I remove all the 
escaped backslashs.
Any idea? Or a definitive fix of the app?

After some digging I found an application that allows you to edit the advanced 
settings for file associations in Windows 7: http://defaultprogramseditor.com/

Once I edited the file association for .ep files and pasted ("C:\Program Files 
(x86)\Evolus\Pencil\xulrunner\xulrunner.exe" "C:\Program Files 
(x86)\Evolus\Pencil\app\application.ini" "%1") pencil now opens my .ep files :)

Actually, regarding comment #6, the key registry entry appears to be

HKEY_CLASSES_ROOT\ep_auto_file\shell\open\command

To fix, run regedit from a command prompt, Edit -> Find, put in ep_auto_file, 
check only the Keys box, and click Find Next.  The first one it finds should be 
the one mentioned above.  Double click on Default in the right hand pane and 
paste in

"C:\Program Files (x86)\Evolus\Pencil\xulrunner\xulrunner.exe" "C:\Program 
Files (x86)\Evolus\Pencil\app\application.ini" "%1"

and click OK.

I'd suggest a tab on the options menu to associate specific file extensions. No?

As it seems normal OS process doesn't associate correctly.
