My Computer Says I Don't Have Authorization to Open Opera

I have used Opera regularly, however, today when I attempted to open the browser a security box opened and it I am not sure of the exact language but it question something about wanting to change access to the Opera Browser, however I closed out of it because I did not want to change it at all. Now, however, I cannot access the Opera Browser because I am not an authorized user. I own the computer, I should be able to be the administrator without all of this garbage about not being authorized to do things, in this case to open Opera. I don't want to Uninstall Opera, I just want my authority to access the Opera Browser restored.
How can I once again become an authorized user for the Opera Browser, since I do own the computer and am the administrator for all intents and purposes?
As an aside, why does this computer keep on telling me that I don't have the authority to look at things on my own computer? [What is the need for all of this super spy security that denies me access to any of my computer files, as I own all of them?]
