Raspberry pi support package incompatible with Windows 8.1. This Error shown while installing.

I was trying to install the raspberry pi support package. However it shows the following error. Firmware download failed: This version of C:\MATLAB\Support Packages\R2013a\wget\wget.exe is not compatible with the version of Windows you're running. Check your computer's system information and then contact the software publisher. PLEASE help me out with this problem!
