Yes often, usually when i keep an exe file on my harddrive which i downloaded long ago, run-on-demand type programs, things which you click to run there-and-then which don't install themselves but just sit around for the next time one wants them. So i have something like that which i first downloaded and ran months ago, and now i feel i need to run it again. I click straight on the exe file, UAC comes up, i often clcik "NO" so i can go back to the folder and just double check the file is correct, it's signature is valid and it's date of creation is one i expected, just to make sure that it hasn't been somehow tampered with in the weeks since i lat ran it. After checking these detaild i then run again and click "YES".
Clicking "NO" on a uac prompt is a pretty common thing, especially those that appear for no clear reason, you should always click "NO" to them until you have worked out the caue and what is trying to run so you can rationaly decide whether you should let it.
