Hi. Looks like You try upload zip file on ACP. First you need unzip archive with addon. There are xml file and folder callded "upload". So, you need upload files and next choose xml file on admin area.
First you need upload files from uploud dir too the hosting, using any FTP client. And then install addon via Admin Panel. Please make sure that dir /library/Akinak/ManageFakeUsers exists on Xenforo install dir.
