Thank you.

In my particular case installing the Visual C++ 2008 redistributable allowed clickonic-1.1 to load without error, but none of the icons in my desktop folder worked - hovering over shortcuts showed captions saying they weren't valid shortcuts, right clicking on them then viewing their properties showed empty destination fields; double clicking on icons for PDF files actually stored in my desktop folder (so not shortcuts) would load my PDF reader, but it said the files I was trying to load were invalid.

I deleted the entire clickonic registry key then refreshed. While I had to move the icons back to where I wanted them, the icons worked.
