Lightroom Photoshop and Camera Raw Converter

Hi,

I use Adobe creativ Cloud with Lightroom 5 and PS CC CS6. And I installed Topaz Adjust as a Plugin. On my Computer is Windows 8.1, 64 Bit installed,

I tryd to open a Photo *.CR2 in order to develop it with the Camera Raw Converter from PS CS6, but the converter does not start, it opens only PS CS6

Can any body help me with this Problem?

Thanks a lot,

Trusty
