Cannot start Syder 3.3.1 on Windows 8.1 PySide.QtGui import error

[sebastian06]

Hi guys,

I try to start Syder 2.3.1 on my Windows 8.1 64bit, but I always get an error message. But my PySide seems to be OK. I do not understand, why it says: DLL load failed: %1 ist keine zulässige Win32-Anwendung. The --reset options gives the same error.

I cannot remeber, that I did not install any 32bit appliactions ....

Console Output:

Microsoft Windows [Version 6.3.9600]

I meant Spyder 2.3.1 ... of course.

So how did you install Spyder?

Well somewhere in the Spyder, PySide, Python chain you have a 32/64 bit
mismatch. Looks like Spyder is 64 bit so I would check the PySide and
Python.

For PySide I would do:

pip show PySide

For Python I would go back to the installer program to see what it
installed.

Hi,

I've seen this problem before and I think it's related to an antivirus blocking problem. If you have Norton, please remove it and try to install a different antivirus.

Cheers,
Carlos

Hi Carlos,

I do not use Norton but Avira Antivirus. And to remove it, is no really a ggod choice, since this a licensed version with a yearly fee.

Does this mean some important parts of the code are removed by the anti virus SW? And are there any other workarounds, like telling the antivir SW not to block something?

First it has not been determined that it is a AV problem. I would still
verify the 32/64 bit status of the software you installed.

Second as regards the existing AV software, I would at least temporarily
turn off what ever Avira calls their live scan. That part of the
software that scans programs as they are loaded.

Hi,

Adrian is right, first you have to determine that you installed correctly all the main components (Python, PySide, etc), i.e. all of them need to be compiled for the same architecture.

The antivirus idea is just a hunch. The problem could be that the antivirus blocks loading a library when another program tries to load it indirectly (or not using the Windows API, I don't know, I'm far of a Windows expert :-)

Cheers,
Carlos

Hi guys,

I downloaded the required libraries and  reinstalled everything again and now Spyder starts :-)
 

Thanks,  Sebi
