.. note::
It is easier to install OCRmyPDF on Windows Subsystem for Linux.

Administrator privileges will be required for some of these steps.

* Tesseract 4.0 or later
* Ghostscript 9.50 or later
You can install these with the Chocolatey package manager:
Using the `Chocolatey <https://chocolatey.org/>`_ package manager, install the
following when running in an Administrator command prompt:
* ``choco install python3``
* ``choco install --pre tesseract``
* ``choco install ghostscript``
* ``choco install pngquant`` (optional)
Also consider adding:
The commands above will install Python 3.x (latest version), Tesseract, Ghostscript
and pngquant. Chocolatey may also need to install the Windows Visual C++ Runtime
DLLs or other Windows patches, and may require a reboot.
* ``choco install pngquant``
You may then use ``pip`` to install ocrmypdf. (This can performed by a user or
Administrator.):
Windows 10 64-bit and 64-bit versions of applications are recommended. Earlier
versions of Windows and 32-bit versions of these programs are not tested, and not
supported at this time.
* ``pip install ocrmypdf
OCRmyPDF will check for Tesseract-OCR and Ghostscript in your Program Files folder.
If they are in some other location, you may need to modify the ``PATH``
environment variable so Tesseract, Ghostscript, and other any optional executables can
be found. You can enter it in the command line or
`follow these directions <https://www.computerhope.com/issues/ch000549.htm#dospath>`_
to make the change persistent and system-wide.
Chocolatey automatically selects appropriate versions of these applications. If you
are installing them manually, please install 64-bit versions of all applications for
64-bit Windows, or 32-bit versions of all applications for 32-bit Windows. Mixing
the "bitness" of these programs will lead to errors.
You may then use pip to install ocrmypdf:
* ``pip install ocrmypdf``
OCRmyPDF will check the Windows Registry and standard locations in your Program Files
for third party software it needs (specifically, Tesseract and Ghostscript). To
override the versions OCRmyPDF selects, you can modify the ``PATH`` environment
variable. `Follow these directions <https://www.computerhope.com/issues/ch000549.htm#dospath>`_
to change the PATH.
