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?
