This utility has worked for years and now it doesn't. I think the culprit might be an update to Windows 10. It seems like a permission issue and I do run it in administrator mode. In any case, the utility starts up fine, I click update, I get download completed, and then,... when I click "Update Me" and i get : "Error copying file C:\Windows\System32\Drivers\sbigu64.sys The process cannot access the file because it is being used by another process. I've rebooted several times and get same error with fresh reboot. Any thoughts? SBIG 64-Bit Driver Checker Archive Version 4.05 Build 0 August 15th, 2018
