I installed the latest version of CCleaneer on a WIndows 8.1 laptop. Everytime that I boot the computer or open the program I get a "User Account Control" dialog box and the mesasge "Do you want ot allow this progrram to make changes to your computer?". Is this normal (it's distracting and bothersome)? If not, is there a fix. I tried deleting the applicatiion and re-installing without success.
