Possible virus in installer or issues with download server for installer

I just went onto the main website (getgreenshot.com) and clicked the Download link.

It downloaded one file (Greenshot-INSTALLER-1.2.8.12-RELEASE) that Chrome immediately warned me could "harm my computer." It is not signed with the Greenshot cert.

I downloaded a second file by clicking the SAME Link, and it directed me to Greenshot-INSTALLER-1.2.9.129-RELEASE, which was signed and did not give a Chrome virus warning.

And here is the unsigned file location:
