how can I make my lightroom 4 support my raw files from new canon 7dII?
You need to upgrade (purchase) either Lightroom 6 or Lightroom CC
you can download the free Adobe DNG Converter and use that to convert your RAWs into DNGs, which can then be imported into LR 4.
Lightroom 4 does not supports Canon 7dII
You can convert your RAW files to DNG and then import them in Lightoom.
DNG Converter 8.7
Mac – http://www.adobe.com/support/downloads/detail.jsp?ftpID=5854
Win – http://www.adobe.com/support/downloads/detail.jsp?ftpID=5855
Camera Raw plug-in installer
Else you can Upgrade to Lightroom6/CC
Hope this helps
