Hi all, I have a USB bluetooth hardware device that I would use it before without problem. When I would put it into the USB port , the machine would install it's program automatically and I could use it easily. This time that I reinstalled Windows 7 I used the Driverpack for installing drivers. That pack installed a program named "Bluetooth Stack for Windows by Toshiba" for that USB hardware device. And now neither I can use the bluetooth nor I can uninstall that program. Now I want to remove it but I get error (image 2)!! Any solution?
