Always found Norton very good at reporting false positives and pretty unimpressive
at removing anything it did 'find' and a big resourse hog.
Found the culprit. It looks like Norton was removing the installer exe from the folder. I turned Norton off installed and I'm now running 486.
Sorry about the confusion. All the other updates worked with Norton running. Even stranger is that Norton didn't alert that it was removing it. I looked at the history and it removed both for low reputation..
Strange because I cannot reproduce.
Can you try with 486?
I've done an automatic download from with in the program and downloaded the zip from the web site both don't install 485.
I've manually deleted the folder in the programs folder and removed all references to webdownloaderwpf in the registry. When I run the program it still comes up as 484.
Another thing I noticed is when I double click to run the install exe from the extracted folder it vanashes from the folder.
