Flash Player is only detected when rund from 'Administrator' (Windows 10)

I run Windows 10, where Flash Player is supposed to have come

integrated with both Microsoft Edge browser and with Internet Explorer browser.

On my LapTop / Windows 10 exist 4 different User profiles, among which only one is an 'Administrator'.

Adobe Flash Player appears to be detected as 'present' only when working from the 'Administrator' user.

When working from the other users, system says 'this program requires FP to be installed'

even when FP is enabled. This occurs both i Edge and IE.

What can I do to make FP work from the 'not-admin' users as well ?
