Hi,

This is very likely caused by the switch to 64-bit. The following is what has fixed similar problems for the players I've been in contact with:

1) We forgot to include the needed x64 visual C++ redistributable. For most people this seems to make the game crash before the launcher even pops. It should be there now so you should be able to get it by reinstalling the game and install visual C++ when prompted. You can of course also get it directly from Microsoft.​

2) Disabling all mods​

3) Making sure drivers (especially the graphics/video driver) are up to date.​

4) Updating the OS itself.​

5) Removing all game files and doing a full reinstall of the game. If you try this don't forget to make a backup of any saves, settings etc. that you want to keep.​

If you could try the above and let us know if it fixes the problem for you that would be of great help!
 
Ok, I think the 2017 version should be enough as long as it is x64.

Do you have any anti virus software installed and if so could you try either temporarily disabling it or white listing Steam and CK2 in it?
