The window warns you that YoWindow has been downloaded from an unknown source.
It is time to get rid of the warning.
I have gone through quite a complex process in order to do this.
I had to prove that I am who I am to a company issuing certificates for software.
I've been sending them scans of my documents, my photo, even my mobile phone contract.
In the end they have called me and I have confirmed that they were calling to me

And after that I had to pay them money for "issuing a certificate".

In this build I hope you will notice that the warning is gone.
Instead you should see an information box with my name as a publisher.
Unfortunately I was not able to sign YoWindow with "Repkasoft" because we did not register a company with this name.
They could only sign it with my name.
I hope the customers will not be distracted.
Guys, let me know your experience with this build please.
Do you see the warning when you run yosetup.exe?
