Wow, this is PowerPoint 'thing' is frustrating. Outside of uninstalling and reinstalling PP, I'm not sure how we can get this fixed. AFAIK, there is no PPCORE.DLL located anywhere else besides in Program Files, so the .dll must be located and registered from that location.
As to Java, if it will not update, then strongly recommend that you uninstall it from Programs and Features in Control Panel as all of the recent updates for it are Critical Security updates for remotely exploitable vulnerabilities.
If you need it installed, then be sure to install the most recent release for Windows x64. Here's a link from which you can download and save it -
Java SE Runtime Environment 6 Update 26
When the download completes close all open programs and browsers.
Right click jre-6u26-windows-x64.exe and choose 'Run as administrator', agree to the UAC prompt.
