Error occured when start openopcservice, which was complied to EXE by pyinstaller

[Ansonmo]

I used CMD to run "python zzzopenopcservice.py install" and then start the service, it works well on NON-DCOM mode.
When I complied it to EXE by pyinstaller. it can be installed as service well, but can not be started. I check from the log, it said" The instance's SvcRun90 method failed." "Pyro4.errors.SerializeErro:serializert"json' is unknown or not available."

If anybody successfully compiled it to EXE by Pyinstaller and solve the problems, thanks a lot in advance.

I ve seen there was a pull request that fixed the issue. Wouldn't it be nice to include those exe files in the repo ?
