Massive expansion packs 2nd install

Hi all.

1st posting here...here's the sketch...

bought massive and got the expansion packs 1 & 2 & installed them all successfully on my pc & used within logic v 5.5.1. with no problems.

I have just got a mac pro & logic studio, installed & activated massive & its all fine. However, I cant remember when I downloaded the 2 expansion packs onto my old pc whether it gave me the option to download them as windows or mac files! What I downloaded & used (& still have on my old pc) are win zip files!

So my query is this....are there 2 different download options for the expansion packs, or can I somehow just copy the winzip files from my pc to my mac pro & then install them onto my mac ( & then hopefully Massive will "see" them & add them to its library as expansions 1 & 2, as windows did when I first installed them)? I was using them on my pc thru massive not Kore.

As a complete nooby to mac I just wanna make sure before I try; cant find an answer to this on NI site.

Thanks in advance,

Andy
