It looks like you have bought iVIBRATE Pro Edition, whereas this is the project page for iVIBRATE Ultimate Edition. iVIBRATE Pro Edition is a deprecated version that is no longer supported. iVIBRATE Pro Edition is provided as is, so if it does not work for your system unfortunately there isn't anything I can do about it as it is an old version of iVIBRATE running on an old input system.
The only thing I can suggest if you cannot get it working on your system is to contact Itch support here and request a refund. If you are still interested in iVIBRATE, you should try out the demo versions first to check for compatibility before purchasing. :)
