I am having trouble while installing the student version of Simulation CFD 2014. I have windows 8 as my operating system. I dont know what I am doing wrong. In the installation it shows a small message and then it uninstalls all the files it installed in the process showing in the end that installation failed. Please help me out. I even tried restoring my computer to previous date and again tried installing but it did not help. I have attached the screen shot of installation error.
