Hey
yesterday I downloaded ultrastar 0.7.1 and it worked fine,
but after i saw 0.7.2 i installed it and it just dont open.
I click on it it asks for permission i allow it them my kaspersky(anti-virus) says that it wants to download something and i allow it again and then nothing happens.
I tried reinstalling this one and installing 0.7.1 again but even 0.7.1 wont work anymore
any idea what it might be?

Remove all the songs from the game and try to run the 0.7.2 version.

Didn't work
My anti-virus wants to download a ZLPORTIO.SYS
maybe that is the problem

zlportio.sys is the library used by the game and is in the game directory installed along with the game.

Lolol
It was because i didn't have the mic on
stupid me :I
