Installation issue on Unity 2017.1

[aidesigner]

Just purchased Obi Cloth and imported into an empty project (Windows 10). I received 2 types of errors, and the dll error vanished after restart. Then I had case sensitivity errors (Images below). I have seen this before with another asset, where .MAT files were all caps but the meta files where Camel case. I deleted all the meta files and they came back all caps. As a result everything is working, but I would like to know what is happening for the future? Perhaps all caps needed to be avoided for some reason.
