Hi Mikolajek, it is possible to download and install the driver-only package instead of the full version Intel® PROSet Wireless Software. You just need to download the smaller file depending on your adapter and operating system architecture. If you need assistance choosing this package please provide the wireless adapter model and operating system (32 or 64 bit).

In regards of Intel® PROSet Wireless Bluetooth* Software, I am afraid we only provide the option to install the software completely.
