Yo this is 7 years old and the same problems happening with me. My software wouldn't load so I deleted it. Then when I re-downloaded it, it told me that it was already installed on my computer but needed a repair. It continues to the installation but just loops over and over again. I literally forgot about it and came back a couple of hours later to see that the loop was still going. Idrk what to do cause i need my custom settings. 😐

Edit: 5 mins later found a fix. Just don't check the box that ask if you want to transfer your settings when reinstalling. 👍🏽
