File 2015 return

I want to file 2015 return for my income in 2015 and I just purchased your product.  

However, I have my company computer only and it is not allowing me to run .exe file to download turbotax software.  

My company will not give me admin right to run any kind of .exe file.  How do I file my 2015 return.   

Do you have something like 2016 return where I can file on your website.

Thanks
