Activation Kit error 404 - decided

I uploaded the Activation Kit to the server and received an error of 404. The address is registered correctly. The same error is output from the browser. What can I do wrong?

Decided:

I upload Activation Kit to http://domain/activation/
But true folder that insert to XLS Padlock is: http://domain/activation/dovalidation/
