Install button didn't work

I followed the engine installation guide, but I could not download it properly.
I tried the install button but there is no feedback.
What should I do ?

I got a same problem (someone recommend me this: install as permission of administer) but still can’t solve…

Did you try the troubleshoot option on the Settings tab ? The version number seems wrong to me it should be 4.22.3 did you try to run the launcher as administrator ?

I tried, but I could not solve the problem…

I tried the same with you, but it did not work out… :frowning:

Can you try to disable your Antivirus or Firewall ?

I tried. But it did not help solve the problem. :frowning:
(I am not a genuine Windows user, can this be a problem ?)
