Pyjnius Installation on windows 10 64 bit

[David Akinpelu]

I am unable to install pyjnius on a windows machine using `pip install  pyjnius`.

I have jdk-20 and jre1.8.0_3.61 installed. I got the following error

```

I don't know the answer to your question.

But just in case this is to use the Android api (which is what almost everybody uses it for) - that api is not executable on platforms other than Android (so not Windows). See https://github.com/Android-for-Python/Android-for-Python-Users#pyjnius  If this is the use case, the answer to your question is not going to help you.

I noticed that you are using conda environment. Did you try to install the package through Conda?  https://anaconda.org/conda-forge/pyjnius?

@echidne. Installing the package through Conda works. Thanks!
