Can anyone help with installing NAV 2015 RTC on a user's PC?

Hi,

I've installed the RTC no issues for plenty of users in the past, however I can't seem to figure this one out. Whenever I go to install the RTC on the user's PC, this error appears:

I have obviously installed Visual C++ Re distributable:

I am currently running Windows 10 x64 and have had no issues on many other user's PC's here in the office.

Thanks.
