Font changes from Mac to PC

[SteveK]

Hello,

I have a Mac G4 with operating system 10.3.8. I have the Adobe Acrobat
version for OSX. I have 2 problems:

1) I am inserting powerpoint slides into a word doc. I convert the word doc
to PDF. Some of the slides appear, some do not. Do you know of a fix for
this?

2) I have converted powerpoint slides created on a Mac in Arial get
converted to Times Roman on a PC . How do I prevent this from happening?

Thank you.
