I had the same problem as shown at the top.
Before I extract the nexus2.zip file from the direct download, the file is about 5 gb big.
As soon as I extract the file with 7Zip (already tried WinRAR), it says awesomium.dll is corrupted.
.
Then when I look in the folder I see that every file has no KB except for the awesomium.dll file.
For that reason the .exe doesn’t work.
