Important Computing Aspects
---------------------------

You need to understand the following points related to your computer and
operating system.

* 64-bit vs. 32-bit

  Since most modern computers use **64-bit** central processing units (CPUs),
  and most modern operating systems are able to make use of the enhanced
  capacity of these CPUs, we always provide ChemApp for Python in 64-bit form.
  **32-bit** versions of ChemApp for Python do not exist.

* Operating system (OS)

  We provide ChemApp for Python for use on two operating systems, namely
  **Windows** and **Linux**. **Mac OS** is not currently supported.

* Python version

  Due to the slightly sensitive approach of fully compiled python code, the
  ChemApp for Python package should only be used with Python versions that are
  exactly, even down to the minor version number identical to the one that we
  provide. This may be slightly less flexible than many other Python packages.
