Hello, I suggest that you try the following: ```auto conda search cdo --channel conda-forge ``` ```auto conda config --add channels conda-forge conda config --set channel_priority strict ``` ```auto conda install cdo ``` Let me know if that works for you. You may also want to check out the information here: > **[GitHub - conda-forge/cdo-feedstock: A conda-smithy repository for cdo.](https://github.com/conda-forge/cdo-feedstock)** > > A conda-smithy repository for cdo.

Hi [shapara17358official](https://forum.anaconda.com/u/shapara17358official), Currently you’re trying to install CDO for your Windows OS. According to conda-forge’s repository, there’re currently no binary tar balls available for Windows. (see image below, and the OS’s available) ![image](https://europe1.discourse-cdn.com/anaconda/original/2X/c/c6e09f743112f1633905ad33abe04e16aa49751f.png) ---

Still same problem is arising. Can it be used on windows ?? ---

Is there any package through which I can use it on windows ?? ---

Quite likely that you need to install it via Pip instead of conda, using the tar balls [here](https://code.mpimet.mpg.de/projects/cdo/files). It’s not recommended to mix between the two, but if there’s no other way, then that’s what you’d need to do. Be careful, because then the dependency solver for that environment will be “contaminated”, and you need to do lots of things manually. It should still work, however. The best case scenario, if you really need it on Windows via conda, is to get the CDO source code and build the conda package for windows. (Here’s the [how to](https://github.com/conda-forge/cdo-feedstock#updating-cdo-feedstock))
