OK so this is the skinny.
Youi have to do this on a computer that does not have Python installed on it. it's an intertwining issue

But if you grab any of the recent appveyor builds and install it you will be met with some ugly red.
but this error is very misleading. and it took me a while to track down the problem...

but this is how i managed to find the source of it.

if you open the system plugin init and move all of the import to below the register plugin. and leave the import eg above it

then run eventghost you will get the true source of the problem.

Error loading plugin file: C:\Program Files (x86)\EventGhost\plugins\System

    import six
ImportError: No module named six

I know there was someone in the forum complaining of this issue. and again a second person mentioned the issue but had said that they tried with appveyor builds as well. so i started snooping and installed an appveyor build. and low and behold there was the problem...

now I do not believe we are not experiencing these problems because we have six installed into python and not into EG but EG will still load it because EG now grabs the python site packages

which is why i think it is a horrible idea to have it set up to do this. and I do believe I have mentioned this kind of an issue happening because of it. Package Installer built into EG is the way to go.

I have not gone through the legwork of making a fix for it as of yet. but I am sure it is as simple as adding six to the dependencies.


the fix is simple a copy of needs to be added to the lib27\sitepackages folder...

but I now have another error. and I am not sure if this is specific to my computer or not

maybe someone can test this and see if they get an error as well


Yup that fixed it...

need to add to the lib27\site-packages folder.

I can confirm it. The qrcode module needs it. I'll make a PR.
