The version variable value shows , which in this case it isn't taking the ActiveXObject above and placing it like the other instances i've created. So far I've only noticed with doing a local with PowerPoint.

This looks to be a syntax issue with Powerpoint's Struct. If you update line 35 obj to objOffice, it should work. Can you confirm this worked for you before I push the fix.

I can confirm that fixes that piece, but it doesn't change the Access VBOM value to 1 so it doesn't execute the shellcode

Yes, I understand, but it isn't actually changing the value as I am watching ProcMon and validating in regedit.

Your right, it looks like this is something to do with PowerPoint has changed. Test with Excel with no issues.
