Hi, I'm using Acer E110 mobile and HP Laptop. For connecting to internet i installed pc suit for that mobile. But my phone modem is not detecting in windows 7. An error occurs during the 'Acer Netchip Gadget Serial v2.4 ' installation. When i checked the Device manager the error regarding the driver is "Windows cannot verify the digital signature Acer Netchip Gadget Serial v2.4 ".
But it is full functioning in Windows XP.
Please advise..
