issues with windows 7 installing anything

I have been having issues with installations of any software on windows 7. I do not know when the problem began, but I first noticed it last week when I tried to install Microsoft Visual Studio Community 2015. The installation ran to 99% and then just kept ruing in perpetuity without completing. I ended up having to end the task in order to regain use of my pc. This week I attempted to install TurboTax and ran into the same issue, install to 99% and then it just stalls. Any attempt to run an installation after ending this task fails to even initialize. When I attempt to install Msft Vis Studio I get an error that another installation is in progress. But it isn't.

From what I have gathered there seems to be some issue with my msiserver service. It will start ruing and then just doesnt stop. I caot stop it regardless of what admin or ownership roles I assign. I am not a computer expert so I am at a loss at this point. Any help would be greatly appreciated.

I am on windows 7 enterprise.
