Thank you yes we realize the file is damaged as this is what the message tells us.
Sorry, I didn't mention that we are trying to download the adobe air plus the Docrafts digital designer program straight from the internet sites.
My friend's laptop is running Windows 10.
I also have problems trying to download adobe air to my laptop running Windows 10 also my MacBook Air, I already have the program digital designer installed thankfully but concerned how I would manage if my computer crashed.
I am sorry I didn't give all correct information in my earlier message this is the first time I have 'posted' on the forum.
Thank you for any help.
