Welcome to the forums,
Riff45!
Can you please be more specific about the issue you're seeing? Where are you in the game? White Orchard?
Also:
1.) Are you using any mods, or have you ever used any?
2.) Ensure the game is not installed anywhere under
Program Files or
Program Files(x86).
3.) Add the game's installation folder and
...Documents\The Witcher 3\... to the exceptions list for your anti-virus software.
4.) Run a verify / repair via Steam / GOG / Origin.
