Fusion 7 & 8 zip download file corrupt

I tried to download Fusion 8 beta and then 7 after 8 didn't work but both zip files (opened with WinRar on Windows 10) seem to be corrupt. The message reads:
C:\Users\Administrator\Downloads\Blackmagic_Fusion_Windows_8.0b3.zip: Unexpected end of archive
I've tried WinRar's inbuilt zip repair and also several other programs that claim to be able to repair zip or rar files. None of them have worked.
Is there any way of just downloading the .exe installation file for either 7 or 8 so that I can install it normally?

It could be your connection is shotty, or your HDD may be having issues, or possibly a memory issue. I'd recommend downloading it again, maybe to a different drive. Also, check your C: drive for errors. A zip file cannot be repaired if it is downloaded and saved as corrupted. Downloading an installer .exe won't help as chances are it will also be corrupt, just like the zip files.

Thank you very much for your help and quick reply. I simply changed the download directory in Chrome to another HDD and it unzipped without any problems.
