Hi everyone
I am using Python 3.6 on windows and having problems with some API code that I was provided from a Website that uses what they call the LexActivator.
Basically they provided me with this dll and the code required to load this dll and then use this for authentication of products. Unfortunately they do not seem to be able to help hence the reason I am here.
I have 2 files all in the same project folder as below so as you can see I have used the simplest relative path for the dll
1. LexActivator.py that is suppose to load the dll below
2. LexActivator.dll
The error I am getting when I run the code is as below, it is as if it cannot open and load the dll?
Thanks
