I can't seem to get the 9.1.1 zip or 9.8 zip either. I'll let the Powers That Be™ know.
Did you try Help>Updates from within photoshop cs6?
If that doesn't work, try this 9.1.1 camera raw plugin installer
Thanks for the tips.
I did run the update and I was able to download alternative link.
But running this patch did not resulted in beeing able to read the Sony RAW files...
You now need to convert your Sony raws to DNG since CS6 won't take Camera Raw 9.8 which supports your Sony a 6500.
Adobe Digital Negative Converter 9.x See this link for the latest converter and instructions on how to use it.
The download link for the DNG converter works.
