Hi Jesim, what software application are you trying to use?
I added possibly relevant information below:
There is a newer version (15.3.1) of the Intel(R) PROSet/Wireless Software available for your system. However when moving between major versions like 13.x and 15.x we strongly recommend that you completely uninstall the old software before installing the new one.
This can be a complicated process and you may want to contact support for assistance.
