When I try to open in I get a window titled Warning. In the window it says "The following disk images couldn't be opened." The reason stated is "illegal seek".

I also tried to open it through Disk Utility. I get the same result.
"Unable to attach "Pro_Tools_10_3_5_Mac_79249.dmg." (illegal seek)"

Hi, you might try downloading it again in case the first one was corrupted somehow.
