Downloading Silver FX pro to an iMac?

I am trying to download my Nik Silver FX Pro boxed edition; I had removed it a while ago. I now try to re install it on my iMac and I read that i need an operating system of 10.4 or newer. I have Safari 10.12.6, yet in will not load, even when it had before I upgraded to 10.12, 6 Any help would be appreciated.

-First, you posted in “vote” which is wrong place for your question.
-second, what is boxed edition? Nik come as package of 7 plugins. You can download them from your DxO account.

You need OS X 10.12 and above.
