I did a Google Search and it seemed to suggest that PanoStandAlone might have something to do with an HP camera. So if you have HP software installed then 'maybe' you need to do what it says to resolve the issue. As a further note, I use a free program called EasyCleaner. It is a very good registry cleaner. If you decide to use it, just download, install and run it and click Registry, Find and then Delete all and close.
My Dell Inspiron 1150 laptop with Windows XP SP2 installed was running slower and slower.I recently purchased and downloaded a registry repair program called RegCure to fix the problem. A free screening had supposedly detected over 1100 registry errors. After I downloaded and ran the program and apparently corrected all the registry errors, a Windows Installer window kept opening to install something called PanoStandAlone. It would get as far as the prompt to insert the installation CD, which of course I did not have. I was unable to close the window without the installation process restarting immediately. This went on and on. I searched for any PanoStandAlone files, hoping to delete them, but all searches of my hard drive turned up nothing. I finally restored my computer to an earlier setpoint, which removed the RegCure program and fixed the problem, but of course my computer still runs as slowly as before. What is PanoStandAlone? Why did my computer keep trying to install it after downloading and running the RegCure program and how do I fix this problem so I can run RegCure? Technical help at Pareto, the company that markets RegCure, has not responded to my request for help.
