Looking on the web, I noticed those errors are not rare and there were plenty of suggestions, on how to fix them. I again received the above "Visual C# 2015 compiler could not be created" error. If I looked into the solution using Windows Explorer, I noticed the files were created for the project, so I tried to add an existing project to the solution, but that didn’t help either. Prior to doing this I was receiving a dialog to sign in and that my license was invalid no matter how many attempts I made at logging in with my enterprise issued MSDN account.Error "Project could not be opened because the Visaul C# 2015 compiler could not be created. This allowed me to repair visual studio and inevitably re-update my licensing information on visual studio. From here I right-clicked the installer and ran a repair(you can choose to install, uninstall, or repair).

What I had found was a reg key that led me to an idea of how to repair VS from an internal installer. I attempted to run a repair from "programs and features", run setup.exe from the ISO mounted to a drive on windows and even tried to run it from a disk and I couldn't get anything to run. In my scenario, I had just performed a user migration from one PC to an AWS instance and was not able to use VS 2015 Enterprise edition upon migration.
