Thanks spearson I did try that and it did end that error when installing. I didn't know about the Wow6432Node folder in my registry, as the error I was getting looked like it was pointing to /SOFTWARE/Intel. At least now it installs without an issue.
Unfortunately the issue with the busy spinner not going away still remains and I have no idea. I've uninstalled, reset my fan and monitoring settings, then reinstalled again. I thought for sure that error was somehow related, but now I have no idea what the issue is at this point.
