# Orekit Installation on Windows
## Versions

- Python 3.11.4
- conda-forge:
- orekit 11.3.3
- jdk 1.8.0_332

## Installation step
Run everything in administrator mode.

### anaconda3
1. Follow [this video](https://www.youtube.com/watch?v=_JXGBk_KwZc).
- My solution to avoid the ["Anaconda Installed but Cannot Launch Navigator"](https://stackoverflow.com/questions/44841470/anaconda-installed-but-cannot-launch-navigator) problem is to have the **Getting Started with Anaconda** option checked at the final step.
2. Launch **Anaconda Prompt** in administrator mode. In **Anaconda Prompt**, do the following installs:
- orekit
`conda install -c conda-forge orekit`
- mlb_toolkits basemap (optional)
`conda install -c conda-forge basemap`
- cartopy
`conda install -c conda-forge cartopy`
### orekit
Using [Example Track Corridor](https://gitlab.orekit.org/orekit-labs/python-wrapper/-/blob/master/examples/Track_Corridor.ipynb) as an Example
##### Possible problems and fixes
- `error: jvm.dll could not be found`
[(ref)](https://gitlab.orekit.org/orekit-labs/python-wrapper/-/wikis/faq) Launch **Anaconda Prompt** in administrator mode. In **Anaconda Prompt**, do the following settings:
`set JCC_JDK=C:\Program Files (x86)\Java\jdk1.8.0_332`
`set PATH=%JCC_JDK%\jre\bin\client;%JCC_JDK%\bin;%JCC_JDK%\lib;%PATH%`
- `error: orekit-data.zip not found`
Download orekit-data-master.zip as instructed. Either of the following way works:
1. Download from [orekit gitlab](https://gitlab.orekit.org/orekit/orekit-date) and put the .zip file at the same location as the code.
2. Run following python script:
`orekit.pyhelpers.download_orekit_data_curdir()`
