Spyder fails to start

[GoogleCodeExporter]

What steps will reproduce the problem?

1. Install WinPython portably in user home directory
2. Double click on Spyder
3. Spyder fails to start

What is the expected output? What do you see instead?

I expect Spyder to start, but console window flashes briefly (usually empty, 
too), and nothing happens.  Task manager shows no processes or programs 
running.  Reinstall and Spyder works for awhile, but eventually fails to start.

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

2.7.3.3.amd64

Please provide any additional information below.

Problem exists on 3.3Beta on Win64 as well.

I have exactly same problem. I installed WinPython 32-bit on a Windows XP PC, 
it works fine (great actually).. Then I installed it to TWO Windows 7 PC, one 
with Python 2.7 already installed, one with no Python at all, both of them 
return this message when I run Spyder or Control Panel via WinPython Command 
Prompt:
"Syntax Error: Non-ASCII character '\x90' in file . . . on line 1, but no 
encoding declared"

I also have it in my portable drive, and it works fine on both machine. I don't 
get what's going wrong here. Google search doesn't help either.

Thanks for this report.

Could you please attach the full traceback? (Where the error is occurring)

I have the same problem for winpython-64bit-2.7.3 running on Win 8 64 bit. 
After running the batch file spyder.bat in the scripts directory, I got the 
following message:

Traceback (most recent call last):

The 32bit version runs well, though often annoyingly pauses for instance after 
"pl" when typing pl.show()

WinPython Control Panel cannot be started for the 64bit version, too.

After a nice period of time of Spyder working as expected, and seeing some of 
the comments on my original submission, I tried to break it and succeeded.  To 
break it, I started Spyder and while it was still running, attempted to start 
Spyder (light).  Spyder (light) failed to start.  And after exiting Spyder, it 
is refusing to start now as well.  Now I have no idea if it is possible to have 
spyder and spyder light running at the same time, and I can't see why I would 
want to, but I was trying to recreate the problem.  I pretty much doubt that 
was the sequence of events that caused my initial report.

My windows mojo is not good, and I can't capture the console output.  Some 
error message appeared the first couple of times I tried to restart Spyder 
after breaking it, but now it exits before even they can appear.  I tried 
running the spyder.bat to capture the console output but no luck there, either.

Unlike some, the WinPython Control Panel is still starting for me.  In fact 
everything else is starting.

Had the same problem when just double clicking on spider.
Solved it by running Spyder as an administrator.

Re-examined this issue.  Thought 32-bit version solved problem, but now that's 
not working either.  If jlvander's comment is true, then it is likely a problem 
with permissions between spyder and the host OS, although I can't imagine why 
it would work for a time and then stop.  I don't have admin rights on the 
computer I'd like to run this on, so his workaround doesn't work for me.  

Does spyder try to phone home, creating some network traffic that my admins see 
and then block which eventually causes the failure?  Occasionally, I will get a 
notice on other apps that indicate that network administrators have blocked 
some capability of that app, but the app mostly works anyway locally.  Often it 
is some sort of auto-update service.

Same problem here.  What worked for me is navigating to Spyder directory in cmd 
terminal and type "Spyder.exe --reset"

Same problem for me. Nothing started. What I did is add the follwing to 
setting/winpython.ini

PYTHONPATH = C:\WinPython-64bit-2.7.5.1\python-2.7.5.amd64\Lib

I had the same problem of spyder showing nothing for a long time after i 
started. I waited for some time and the IDE has opened....

See issue 53 and 57. With WinPython 3.3.2.1 installed on 64 bit Windows 7 
machine, I downloaded the Microsoft Visual C++ 2010 Redistributable Package 
from http://www.microsoft.com/en-us/download/details.aspx?id=14632, installed 
it and then copied msvcr100.dll from C:\Windows\System32 to 
C:\WinPython\python-3.3.2.amd64 (replacing the file that is already there). 
This seems to solve the problem.

Had same problem on Win 7 immediately after WinPython installation with no 
additional configuration changes. Then ran Spyder.exe as an administrator and 
it launched.

After reading a previous comment, I, also navigated to the Spyder directory via 
the cmd terminal and typed "Spyder.exe --reset".  It worked for me as well.
MAKE SURE TO USE "--" not "-"

I encounter the same problem.  From the popped up window, I could read that 
there is some library that spyder cannot import.

I had the same problem. I would try launching spyder.exe and it would flash up 
the console with some error parsing spyder.ini. It was complaining about a line 
'editor/code co' which appeared at the bottom of the file. I deleted this, and 
then spyder launched

I have a similar problem. I installed Winpython (3.3.5.0 32 bits) to a network 
drive, and added a shortcut to spyder in the users main menus. When using that 
shortcut, an (empty) console opens and closes (I paused it by adding PAUSE in 
the .bat, still empty), and nothing happens. It works just fine for users with 
admin rights, but I cannot give those to students...

I had the same issue on WinPython 64 bit 2.7.6.4.  One day, Spyder just 
wouldn't start.  It showed the spyder splash screen but then minimized to the 
task bar and wouldn't show the actual program.  Like the above comment said I 
opened WinPython Command Prompt.exe and then typed in "spyder --reset" . It 
worked like a charm and now spider will load again.
