I've installed this version of Aura Image Gallery III and it's working as it should: auragallery_v3_2_0_15.exe. Although on the official website it says that Windows XP, Vista or 7 are supported, you can safely install the product on Windows 10 as well. I am currently running Windows 10 X64 Professional and didn't encounter any errors during the installation.
When installing, right click the installation package and select Run as Administrator to avoid any other issues.
