This had been listing importlib_metadata, and its dependency zipp,
because it's a dependency of newer 'keyring'. As we're hard-coding an
older 'keyring' without that dependency we don't need to list them here.
* WiX Toolset 3.11.2
* WinSparkle 0.7.0
NB: There's a need for a specific/older version of two python modules:
certifi and keyring, else running EDMarketConnector.exe doesn't work.
Unless I'm mistaken about the source of some necessary software/files,
or someone can only find a later/different version of them, this should
now serve as an easy guide to making EDMC releases.
