What DNG version for olympus stylus 1 on photoshop?

Hi all,

Hope someone can help me.

I'm running OSX 10.7.5 and use photoshop CS5 and lightroom 2

I want to download the DNG converter to open my olympus stylus 1 .orf raw files.

my question is what version of DNG do i need? i tried to download the latest DNG but

it says i need OSX 10.10 (my mac will only go to 10.7)

appreciate some help on this.

Thanks.
