I have always used .EXE most people say thats not the best way to update but it should work , I have also though that antivirous could cause problems . Last night I was doing a update on my wife's DG45ID sys and forgot my own rule and it proved me right. I downloaded the 135 flie and forgot to disable the Norton and the update would not even run. I think that Intel should Include in the release Notes that if you are going the EXE method, That they disable all security before doing the update because the update gets treated like a virous. I went back and disabled all security and the up date ran fine just like it should .
