DXDIAG is a program you run from the Windows search box on the task bar. After running it will open a window and start collecting info with a progress bar in the lower-left corner. When it completes click the 'save all information' button and save it to a file then attach that file here.

Please attach here your Documents/Paradox Interactive/CK3/pdx_settings.txt .
From your Documents/Paradox Interactive/CK3/logs/ folder, attach here system.log , error.log , exceptions.log  

Not enough memory resources are available to complete this operation.

Please:

- expand your Windows paging file maximum size to 32gb

Optional: Increasing the paging file size on Windows computers

On computers that have 8 GB of RAM, the suggested paging file size is 16 GB. www.ibm.com - exit every other app you can before starting the game.

Good luck with that!
