update flashplayer20_d_install.exe not working, COMODO busy

Hello.
I tried to update Flash, downloaded flashplayer20_d_install.exe, started it.

It seems to me like Comodo is checking something and never finishes.
When I close the Adobe Download Manager window, Internet Explorer pops up to my surprise and does nothing too.
Could anyone please explain this to me?
