can't update to 8.1

write the key - work
after that next and it write me always no internet connection
and the internet works! i try to disable comodo internet security and nothing..
and other question: how can i know if my activation its vl or something else?

thanks!

The only way to upgrade to 8.1 is through the MS store. The only other way to install 8.1 is if you're a legit subscriber to TechNet/MSDN and do a clean install with the RTM version or to buy 8.1 full retail from a PC/retail store.

With your broken english/typing it's hard for me to follow what exactly you are trying to do.

i download from this forum the windowssetupbox.exe
i write the right key and its work
but after i click next its open internet error. (no connection)
and the internet works! i try to disable comodo internet security and nothing.

and other question:
my friend buy english version of 8.1 i want install hebrew .. the system interface hebrew but some MS APPS like mail still in english.
what to do?
