Meh, I'm having troubles with downloading this shit, and after googling I see I'm not the only one. I had a few errors while downloading (whole day to download 3gb, wtf?!) but now I finally managed to finish it! I was so excited! WOHOOO!
Then I got this:
"Unpacking File: D:\windows 8\pl_windows_8_x64_dvd_915436.sdc
CRC not valid2"
"Cannot unpack file. Please, download it again."
This was one of those moments I seriously considered throwing my monitor through the window. The Secure Download Manager deleted the SDC file instantly, not even giving me chance to somehow convert it by myself or something like that. The support have no idea how to fix it. People say that it doesn't matter what version you download, it just happens sometimes. For downloading errors they suggested setting a proxy, and so I did. So, now I'm downloading the file again, using default settings. Shit, there is a shining new Lenovo Y580 laying on my desk unproductively, collecting dust, cause I have no Windows on it -.-
Wish me good luck.
