I'm working on a plugin and till now everything worked fine.
But some days ago I rearranged all my files and folders for the plugin and extensions.
Now if I install the plugin and start Illustrator (does not matter which version of Illustrator; I tried 2017 and 2018), I get the Errormessage "Error loading Plugins. XXX.aip". The XXX.aip stands for the plugin I am working on.
Now I can click OK and after that i can see my Extensions, but not the Plugin.
I have no idea how to fix this, because I do not get any additional information about this error.
Maybe someone here can help me to fix this issue, thanks in advance!
I found the right answer myself ... I used the wrong libraries (on a MAC in /opt/local/lib) to start the Illustrator.
In case somebody strugles with a similar issue:
Found out, by starting Illustrator via XCode (Outputwindow shows errormessage).
