Hey, I got the mod, but can someone please tell me how to install it?

When I click these two buttons,export String and import String, it's invalid. Anybody know why? Does this have anything to do with the operating system? I'm using Windows 10.

Hello! My name is Zhulien Lachev. I am looking for link of the amazing mod Hawks Seven years war  but without succes. I like this version so much. 
Can you help me?  If somebody want to share the mod package with me - my email is jujo92@abv.bg  There is a program
wetransfer.com for sending big files. Thank you in advance!

Thanks a lot, looked everywhere for it!

Ok
If you get only things like "knciaicaaoi" may be it's a problem of Characters encoding

When you save descriptive file you can select encoding type as UTF8, ANSI or Unicode
By default it's ANSI
