The guide on the GitHub repository is for Windows 10 users so, 7 may not be supported.
You can, however, check this:
https://bitcointalk.org/index.php?topic=2825916.msg28950183#msg28950183It's about the wallet but If the error mentioned there is related to Python, then maybe it could be a solution (hard to tell as you didn't give much info).
Alternatively, you could create an issue on the
GitHub repo or contact the
developer on the forums (inactive for some time).
Thanks for your reply.
The issue is that after adding Master Public Addresses on a Multi-Sig wallet and entering target for the Bitcoin Directory, when moving the config file onto the .exe app, EPS won't launch at all.
