An error occurred while signing: SignTool.exe not found.
This error popped up tonight when I tried to publish an app via ClickOnce deployment. This was the first time I had tried to publish since building up my latest machine. I had assumed the signing tool would have installed when I installed VS2008 but I was wrong. After seaching around for a solution, I realized that I needed to download the new SDK for Win7.
You can download ISOs or do a Web Setup (which is what I’m doing). The ISOs are
here and the WebSetup is here. I may have jumped too quickly on doing the Web Setup as I have two development machines, my quad core desktop and the netbook. Yes, I do development on a Asus EEE PC 1000HE netbook. I can even run multiple VMs via Virtual PC 2007 on the netbook. It’s a little slow but it works just fine. We’ll see how the installs go.
There’s also a new Win7 training kit available as well. It’s at here.
Enjoy

Installing the Win7 SDK fixed the problem. I published my app on the first attempt after the SDK install without any problems.
