Hi Chris, welcome to PCHF

Do you by any chance know the make/model number of the webcam? If so, I will help you find the latest drivers for it.
Another thing you could try is when it says the camtool is running, go to task manager by right clicking the toolbar and selecting Task Manager.
Then select the processes tab at the top and look at that list for anything gonig by the name of camtool.exe or something similar such as the make of your webcam.
