I am trying to get my Excel VBA code written on a PC to operate properly on a MAC. I have determined that the MAC version is missing key libraries. How would I go about locating the library or at minimum determining if it even exists for the MAC (for example, regular expressions).

On my PC version, I can determine the .dll file associated with each reference.

For example:
Microsoft XML, v6.0 ==> c:\Windows\System32\msxml6.dll
Microsoft Internet Controls ==>c:\Windows\SysWOW64\ieframe.dll
Microsoft InkEdit Control 1.0 ==> C:\Windows\System32\Inked.dll

Should I try and search for these same files on the MAC and then attach them as references. Should I try to find MAC versions? If so, where? I need to provide the instructions over the telephone to the person who uses the mac. I don't own one and do not have easy access to one.

The person would like to use the program without using a windows emulator.

Thank you.
