Windows 10: Default Apps will not allow me to select Opera Browser.

Hi, Yesterday I downloaded the new Opera 36 Browser. I like the look of it and would like to trial it for a while. However when I attempted to set it as default in Settings/Default Apps it will not accept the Opera Icon.
I visited select defaults for Apps and ticked access for Opera but no use - Settings will not accept Opera.
Any help appreciated.
Thank you.

Panic over. After a restart Settings had accepted Opera - don't know why it hung.
Thanks.

Using Opera as default browser in Window 10

Thanks Abdul - the problem persists but maybe with Opera 35 (I'll check on their website). In default browser, default apps by protocol and default apps by file type Opera comes up as an option but when 'selected' does not 'register' as a selection and
the field remains unchanged.

 

Default browsers

I am running Win 10 1709 16299.248 64 Bit

MS Edge Browser

Internet Explorer Browser

Maxthon 5 5.1.6.3000 Browser

Opera 51.0.2830.34 Browser 64 Bit

When I try to change default browser in Settings or Control Panel, the only available Browser selections are Edge, IE and Maxthon 5.

Opera is not displayed for selection as a browser.

I logged out of my main Administrator account and logged into my secondary Administrator account. In the second account Edge, IE, Maxthon 5 and Opera are available for browser selection
and I can select Opera for my default browser.

I have tried uninstalling Opera, rebooting and reinstalling Opera with no change. Opera is still not available for selection as a Browser.

Opera runs as it is supposed to run it just is not recognized in my main Administrator Account as an available browser for default.

Has anyone else experienced this and if so, can you tell me how to remedy the problem in my main Administrator Account?

I am assuming this is a registry error in my main Administrator Account.
