We use conda constructor https://github.com/conda/constructor along with the configuration file located at python-microscopy/construct.yaml to build executable installers for Windows and OSX.

1. Make sure conda packages for python-microscopy, pyme-depends and pymecompress are up to date
2. [optional] Create a clean conda environment (or just install constructor into the conda base environment)
3. conda install constructor NOTE: At one point it was neccesary to git clone the constructor source, checkout the "v3" branch and do a python setup.py install instead of the above. I think that the v3 branch has now been merged into main, but it might be worth trying the source install if you run into issues.
4. Download the latest conda.exe for the platform you are building for from https://repo.anaconda.com/pkgs/misc/conda-execs/ see also conda/constructor#257
5. Change to the python-microscopy directory
6. Edit construct.yaml to set the version to the latest conda package version
7. Run constructor --conda-exe PATH_TO_CONDA.EXE .

• Generated installer on Windows displays a bunch of complaint dialogs saying that it's not working. These can safely be dismissed whilst still resulting in a functional install
• Setting the installer icon is not working
• Might be getting a framework error (or other dependency problem) on OSX (it's been a while since I checked)
• There was a problem with packages wanting to run post-install scripts on OSX (not sure if this has gone away)
