Lightroom is making a call the the AGkernel.dll file but the file is unsure what to do because it can't find the line of code within itself to make a response. This can happen for a number of reasons which fall under these two broad categories: AGkernel.dll is damaged and needs to be repaired or AGKernel.dll is the wrong version and needs to be updated to the correct version.
Here are some things you can do to fix the file:
- Re register AGKernel.dll with Windows: https://support.microsoft.com/en-us/kb/249873
- Repair Windows: https://support.microsoft.com/en-us/kb/929833
- Install all available updates for Windows: Install Windows updates
- Uninstall and reinstall Lightroom
I do have the same problem, non of the above fixed my problem
