Unity 4.6.1 does't download well

I clicked the Download button, started downloading, but when It’s on 0.6Gb/1.2Gb (aprox) it suddenly finishes the download, like if it was actually downloaded. When I click it appears a message from Windows saying Windows stopped the execution because it could damage the computer.

I click to Execute anyways and a message apperars saying that the data wasn’t well-downloaded or something like that. I re-downloaded it 4 times, (3 with Google Chrome and 1 with internet explorer) and the same happens every time.

Thanks for reading and I hope there is an easy answer for this ^^

Ps. I have a good enough computer and internet, Windows 8.1.

Pss. Sorry for my horrible english :stuck_out_tongue:

I’ve had this issue before and it’s not a Unity issue but an OS/Browser issue. With me it got to about 300 Mb and stopped at the same point. It eventually “fixed” itself and until it did I just used a download manager, think the one I used was called FlashGet but there are lots of them around.
if you search for free download manager on Google.
