Unity Startup Error (Copying File/Access is Denied)

Questions & Answers
1

Every time I boot up Unity, the loading screen appears with an error message popping up saying:

“Copying C:/Program Files/Unity/Editor/Data/Resources/Packages/unity-editor-home-0.0.7.tgz to C:/Users/User/AppData/Roaming/Unity/Packages/unity-editor-home-.0.0.7.tgz: Access is denied.”

I have tried Running as Admin, I have tried completely uninstalling Unity (even from RegEdit) and reinstalling, I’ve tried holding Alt on program startup and yet it still continues to happen. My computer was working fine with an older build and I tried to install 5.3.1f1 and this happened.

Pressing “Force Quit” or “Try Again” never works so I have to hit cancel which then puts Unity to this screen, which is never makes it passed.
