Fortunately, I had quickly found the manufacturer's instructions (in English) and could complete the installation so.
The rest was done within 1 minute. Ie Bluetooth on Samsung Galaxy S4 Mini enabled started searching on the PC and it was the phone GT-I9195 shown me after 2-3 seconds.
Direct times all JPG images and other files, a total of 159 files, downloaded to the PC from your smartphone. During transmission, the information of the file to be transferred is in the taskbar (which is, however, Windows settings, depending).
I am completely satisfied and can recommend this Bluetooth Adapter for Win7 systems in conjunction with Samsung Smartphone / Tablet.
