I can't play Overwatch at Windows 7

[account_disabled]

Hello guys!

I am trying to download from the launcher the Overwatch but i got a message which says:

A 64 bit operating system is required to install and play Overwatch.

I have Windows 7 64 bit installed. With the other Blizzard games i don't have problems.

Can you help me ?

Thank You!!!

I didn't find the right solution from the Internet.
