Windows 10 Unable to stop installation by clicking 'No' on the UAC window.

[Abhay Bhatt]

I have the Opera browser setup. When I double click on the executable file, the UAC window pops up, asking me whether to allow changes by this app to my computer. Even if I click on 'No', the setup proceeds anyway and completes.
Why is this happening? Is this a problem? If yes, then what can I do about it? (Bdw, this is also happening with other executables/setups)

Note- I have already tried the following:

so you ran the scan and repair but the system is still mucking up?

 

[pnamajck]

have you scanned your environment for malware or viruses?

accordingly … might take a look at the following website … sub-heading "securing the elevation prompt"

Clicking yes will allow something to be installed system wide, clicking no can still install but it will be virtualized in your user profile in %localappdata%\virtualstore

Yup.

Are you sure? Because I have seen instances where when I click 'No', the installation stops and is not completed.

Depends on the installer
