Zwift won't start

Zwift won’t start. I click on the application, click Let’s go and then quick.
I am using Dell Studio Laptop

Please help

I have the same problem. I have tried a ton of things. It opens but only in a small window, can’t really click on “let’s go” and then soon after it closes…it might go to another screen or go back to sign in but then it closes.

Do you guys have .NET 3.5 installed?

My Zwift App doesn’t start either on my Macbook Pro. 2 days ago I had no problems using it. Can you help??
