Raj,Here is my method.1. Install DPP 4.11.0 from Canon website2. Delete Canon_Inc_IC folder in C:\ProgramData\3. Uninstall the Lens Registration tool.4. Install DPP 4.10.50 from Canon websiteThis gave me DPP 4.11.0.2 and Lens Registration Tool 1.10.3...

Thanks! What version of Lens Registration tool are you using?

Yes I had the same experience. Once the lens profile crashed DPP4 crashed as well and would not open. I'm sure at some point Canon will fix it.

I uninstalled DPP4 then removed all "Canon" folders in Program Data, Program Files, Program Files (64) , rebooted and then reinstalled. It seems to work except for lens profiles.

Crashes after upgrade 
