Cannot Launch Spyder on Windows XP

[Faizan Bari]

After installation of spyder, IDE doesn't launch when I click on the
program. Anybody aware of any issues with the executable ?

Thanks for your help in advance.

[Pierre Raybaut]

Please try to run Spyder from a terminal and post here the traceback
so we can understand what's going on.

On Windows:
* depending on your installation, simply opening a command window
and executing the command `spyder --debug` could work
* if it doesn't work, open a command window, change current
directory to Spyder's (default with Python 2.7:
C:\Python27\Lib\site-packages\spyderlib) and type `python spyder.py
--debug`

On Linux/MacOS:
* open a terminal
* type `spyder --debug`

I had a similar problem a few months ago.  Spyder ran fine on my desktop, but wouldn't run on a laptop; both running Windows NT.  In my case it turned out that it was the Virus program (FortiNet) that was doing it.  You could get it to work by defining an exception.  The laptop has since been updated to Windows 7 and the problem went away (even though it still has ForiNet on it).

Hi Pierre,

I am facing the same problem. Python(x,y) home window appears but on clicking the spyder icon, it doesn't launch. Following is the traceback:

I am using Windows XP. Please suggest what should I do so that Python(x,y) works properly.

It looks like a problem with your IPython installation rather than with Spyder. IPython is failing to find a required DLL for the zmq module. Does IPython run okay by itself if launched independent of Spyder?

I am not sure if this is of any use or help, as the package in question is not the same, however it may be related.

PyTables uses the hdf5dll.dll, and the way that the hdfgroup has built the Windows binary for versions for hdf5dll.dll 1.8.10 causes pyTables to fail to load on Windows XP, while it runs fine on Windows 7 or 8. The error reported is that the hdf5dll.dll can not be found, even though it is in the path. This issue is also seen in WinPython 2.7.5 if the included PyTables 2.4.1 is used, which uses hdf5dll.dll 1.8.10, so it only works if using pyTables on Windows 7 or 8 . On XP the above mentioned error is reported. If the hdf5dll.dll is downgraded to 1.8.8 then everything works on XP as well as Windows 7.

So my bet is the the DLL that is trying to be loaded in this current issue likely has been built in a way that also causes it to only work on Win 7 and not XP, just as the latest hdf5dll.dll also only works with ctypes on a windows 7 and not XP.

Sorry I can not suggest how to fix the issue, but perhaps this info will help someone else be able to resolve the problem.

Sol.

It looks like it could be a more general issue with the Python(x,y) distribution. I would recommend moving the discussion to that forum:

Hi,

I understand that Python(x,y) 2.7.5.0 is not able to run the dll file on Windows XP. Can you tell me any previous version which can work fine on Windows XP. Also, where can I get the installation file for that version?

Hello everyone, 

A solution to this problem with python(x,y) is available there: https://code.google.com/p/pythonxy/issues/detail?id=670

Thanks Sylvain for keeping us posted. It seems Win XP is finally dying :-)
