v45 is Spring 19. If your org is not on Spring 19 you won't be able to access v45 API.
A quick way to see the which version your org is to just log in and see the loading animation.
If this is the animation then you will be able to use v45.
You have to wait till next weekend as Spring 19 will reach all orgs then. Src: https://status.salesforce.com/instances/AP0/maintenances
