LibreOffice not opening following Win 10 Creators Update.

I just finished installing the Windows 10 Creators Update and find that Libre Office won’t open from my standard user account. I can open it by running it as administrator. When I go to open a .doc file the Libre Office icons are missing next to the file in the browse window. The files still open. When browsing the same files within Windows Explorer the correct Libre Office icons are on the files. When I close Libre Office about 10 instances of it continue to run as shown in Task Manager with one continuing to use 33% CPU, each one has to be terminated from within Task Manager. I’m thinking I may need to flush the system of Libre Office and start fresh. How do I do so?

I forgot to note that this is the portable version.
