DxO Nik - 64 bit

Could someone please explain what exactly DxO did re the Nik Suite and its 64 bit architecture? I thought they upgraded Google Nik, which was 32 bit, to 64 bit but elsewhere it is being said that Google Nik is already 64 bit?

Thank you

Hello,

DxO stopped the support of x86 bit systems and continue the support of x64 bit. With the new released version of NIK by DxO users get the most critical issues (I mean crashes, host+plugin misbehaving, support of the latest OS versions and hosts versions) fixed. And this is the first main difference from Google NIK.

Regards,
