I am an ARIS1800 user in an institute in Japan. I downloaded setup.exe for ARIScope v2.5 from this site and tried to install it to my Windows 8.1 PC. However, an error message showed up, which says: "There was an error processing the product information. Please try downloading the installer again.". Our IT guy said the installer program tries to access 18.104.22.168 when double clicked, but this site is not available at the moment. Does that mean I should wait and try installing again? Or is there another solution to this?
