Hi, i have downloaded 3d blender and Python 2.5 and tried to run Python with blender for the use of importing models, but when i tried to import the model a message came up in the command prompt saying :

module use of python25.dll conflicts with this version of python

This error occurs after clicking the button import from the collada blender library and prevents the import of collada files into 3d blender. However when comparing to another computer with the same version of python installed everything is the same to the other computer which works so what would make this computer different (different as in not working)?
Can anybody tell me why or help me to figure it out...
Any help would be muchly appreciated...

A concise technical follow-up relevant to and the earlier suggestions from and .

A DLL conflict like this most often means a compiled extension (.pyd / .dll) was built for a different Python ABI or CPU bitness than the interpreter that Blender is actually using. Windows loads the first matching python*.dll it finds; if that DLL’s ABI/version/arch doesn’t match the running interpreter, the module will fail to initialise.

Quick diagnostic checklist (run inside Blender’s Python console or using Blender’s bundled python executable):

import sys, platform
print(sys.version)
print(sys.executable)
print(platform.architecture())
print(sys.path)

Those values reveal the interpreter version/build, the exact python binary in use, whether it’s 32/64-bit, and where Python looks for extension modules. Also inspect any .pyd files used by the importer (they are compiled extensions) and check for stray python*.dll files in the application folder or system folders that could be shadowing the intended runtime.

Safe remediation and prevention notes:

  • Prefer installing compiled modules into Blender’s bundled Python (run Blender’s python.exe -m pip install <package>) so wheels are built/selected for the correct ABI.
  • Ensure module binaries match the interpreter’s bitness (32 vs 64).
  • Avoid removing or deleting DLLs from Windows system folders; instead fix PATH/loading order or reinstall matching runtimes.
  • For compiled plugins, rebuild against the exact Python ABI used by Blender (same minor version and compiler family) or use prebuilt wheels targeted to that ABI.

Keeping a short record of the Blender build, the Python executable path, and bitness makes future troubleshooting much faster.

I think that definatelly it's a bad version installed.

Try to redownload and install the proper ones.

Cheers and Happy coding

Check if the order of installations (Python first then Blender) makes a difference.
