It has been a month and no answer from the poster. I am in the same situation although for me the EasyUEFI lauches ok, the error comes later.
I have Microsoft Windows [Version 10.0.14393] and version 2.7. Same as the poster I think.
Here is the chain of event: add a new entry, select type (linux), select partition, set a description, browse to select efi.
Then click ok and the error comes (failed to run system API (0x0005001500C60000)). When clicking ok, here is what the log files writes:

When I try to delete an entry I get the same error and the log says:
