Hello, This is very strange issue I ever faced. A Microsoft product not working on Microsoft operating system. I have windows 8 personal computer, a few weeks after installing windows 8 I tried to install Microsoft office 2013 on my computer, the process starts normally i.e I double click on setup then entering the product key then clicking next, now the installation process will be started with a status. Now on my computer, this process stucks in between and won't complete this installation process forever. I need to restart my computer to close that installation window. Please help me how to do that without any issues. Thank you in advance.
