Wanting to free up space on my hard drive, I tried to uninstall several programs that I hadn’t used for a long time through the Control Panel. However, I had trouble with a program called PrimoPDF. When I clicked the Remove button, I keept receive an error message saying that the uninstallation cannot proceed. I searched on Google and found someone said that it would be caused by the missing of some executable files. I don’t know why this happened and how I can completely uninstall this program. Please help me.
