There have been no other reports of problems and no issues here when installing on multiple machines.  My first guess would be antivirus software blocking the install.  You might want to temporarily disable your anti-malware software long enough to install it to see if that solves the problem.  There's never any rhyme or reason for "bad AV software" getting false positives: they just see some combination of bytes in the file and misread that sequence as a threat because they are not scanning a large enough chunk of data.  If disabling the anti-malware allows you to install/run it, please report the false positive to your anti-malware provider.
