software uninstall issue
Acer Aspire 4720Z laptop, Vista Home. I downloaded Logitech webcam software,(no this model doesn't have camera) and it didn't work. I attempted to uninstall it with Vista. It removed one of the icons, not the other. It did not complete uninstall, box with header"Logitech Master Installer" came up, blank, then "MSetup" box with message, redX-an invalid argument was encountered. Logitech Master Installer screen will not close, only mimimize. Have attempted to use other uninstall program, Revo, got same thing, Logitech box, blank and MSetup box also. Have tried to update driver, message states driver is up to date. Logitech webcam icon on desktop opens, quick capture and webcam gallery do not open, preferences box does. Any idea where I can go from here?
