VS2012 in university PCs

Hi, i have started a small course, 8 days, at my local university. UE4.7 installed fine, but the pcs there have VS2012, and getting VS2013 installed its quite a huge problem. Ive tried to see if i can force UE4 to use VS2012 as it did in 4.6, just adding -2012 parameter to the Generate Project files, but doesnt seem to work. The Generate Project Files seems to be searching for VS2013 ONLY and doesnt allow to use VS2012. Is there ANY way to force UE4 to use VS2012 in UE4.7?
