There's no way to physically see that yourself. They do provide the MD5 CRC code: MD5: c18ad8ad161b4f45d9b609ce2b2bdccb, like this one here for the full-version. You need to somehow run a CRC check on the file. That check should match the code and if it doesn't then there's a problem. I don't remember how to do that though.
This is indicative of the corrupted download. The installer got to the messed-up parts and quit.
Before you try this again, run a disk cleanup to clear out your Windows temporary files. There could be some leftover bits in there from the previous attempts and any future attempt will get messed up when you try again. This may not solve the problem now but will help when you try again after you hear back from N3V. They'll contact you soon. Their hours are offset from ours by 13 or 14 hours.
The Disk Cleanup utility is found under Windows Tools on your start menu.
