There seems to be a new IMEI driver at
but will it work with Windows 8.1 Preview?
This is the latest version available of the Intel® Integrator Toolkit. This file will work on Windows 7 and Windows 8 operating system. You can give it a try, but I cannot assure you it will work on Windows 8.1. https://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=22856&lang=eng&OSVersion=Windows%208%2C%2064-bit*&DownloadType=
There are not drivers available for Windows 8.1 yet. That could be the reason why you are getting a blue screen when trying to install this software.
Again, we have no date or additional information to provide regarding the drivers. Once we get them, we will provide them to all users.
