You can attempt a possible recover using an application from this field of work. For instance, I recommend on using Recuva as a recovery solution. You can download the application through the Software's Informer entry. Download and install it and then perform a scan for all files on the driver when the BIR software was installed. If the software isn't listed in the search results, then it's impossible to recover it. Try to install another copy and then transfer the DAT file on the program's installation folder.
