1.65 Doesn't Launch Completely

[mrmonteith]

I've been using older versions of the Arduino IDE. But 1.65 launches, shows "Loading Configuration", and then closes with no error messages. I've tried both the Windows installer and the unzipped version. I've even removed software that I had updated since the version that was working. Still no go. I finally went back to version 1.64 and it works fine.

Here are the system details.
Win 7 Pro, SP1, i5-3470 @3.20Ghz, 8GB ram, 64-bit

1.6.6 is the latest version. Please try that again.

[mrmonteith]

Sorry. 1.66 does the same thing. It launches, I see "Loading Configuration" and it closes.

@mrmonteith Could you try running "arduino_debug.exe" from a console to see if any error is printed?

I'm running Java 8 updated 65. I even removed and reinstalled it. Still have to have to go back to 1.6.4 to run.

@ffissore, @cmaglie, I'll leave this one to you guys from here on :-)

It looks like your windows is missing a "Personal" key in windows registry, under Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders. It should tell us where your "Documents" folder is located. Can you confirm that entry is missing? Any other entry that look like your Documents folder?

[mrmonteith]

It looks like it might be missing. But what's odd is that it works fine with the older versions and haven't had a problem until now.

[ffissore]

Can you tell which windows registry key your windows uses to tell that a folder is your "Documents" folder?

[mrmonteith]

Possibly a My Documents entry. I tried both a Documents and a My Documents entry to see if it would work and still doesn't. Why does the older versions work and the new ones don't.

With the debug it really doesn't tell you what it's having a problem with reading and what. That would help a lot. If I knew what it was looking for and where it expected it.

[ffissore]

The code that's failing is this one: the IDE is accessing your Windows registry, entry Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders, key Personal, to discover where is your My Documents folder
I'm googling for why your windows should miss that entry
