Resolve Won't Run - Error message

Hi All,
Installed Resolve V15 onto Windows 10 Pro HP Z400 workstation. when I tried to run it I got a complicated error message about a procedure entry point not located in the DLL location (see the attachment). As I followed the installer correctly what's happening?
Regards
Andrew
