You absolute unit if a human! It was the permissions. I am the only person who uses my PC there for it only has 1 account and it is an administrator, so I never thought that it would be permissions. Turns out my Temp file for some dumb reason didn't have my account set as the administrator... No idea what that was about, kinda sketchy if you ask me lol. But the install is going through as I type this!
For future reference:
I went to
>"C:\Users\"Username"\AppData\Local"
> Right clicked on the temp folder,
> Click Properties,
> Go to security tab,
> Click Edit, click Add, Advanced...,
> Find now, Search for your account name.
> Click okay
*******Problem solved. *********
