I'm running TeXnicCentre on top of MiKTeX on Windows 10. I have been having some issues with the MiKTeX package manager/updater so uninstalled and reinstalled MiKTeX. That seems to have fixed the issues at the MiKTeX level, however, when I try and compile a document in TeXnicCenter and it needs to install a package a get the following error:

It seems I can install the packages manually via the package manager put not 'on the fly' via TeXnicCentre. Given that I've just reinstalled TeXnicCentre and there are a lot of missing packages a fix for this would be very helpful!

Since you are using MikTeX, you have TeXworks on your PC. Just load your source file in TeXworks and compile it. MikTeX's automatically package handler works from TeXworks, so after one compilation, you can continue editing with TeXnicCentre.
It is many years since I used TeXnicCentre. In those days, you had to configure MikTeX’s automatic package manager so that it not asked for permission to install missing package.
