I've discovered that the problem is not only for sks but for iconpackager too, when i reset data and i reopen the program the updates are avaibles, i run the updates and all seems ok but when i open sks or iconpackager the version is still the first with no update (i've sks with 6.30 and iconpack is 4.10).
I've noticed that these are the only programs that when i install them appear an error-problem writing file, i resume the installation many times and the programs works fine but seems that impulse don't recognize them
