I am getting two errors
1) Cannot publish because a project failed to build.
2) An error occurred while signing: SignTool.exe not found.

Regarding #1, I can manually build and rebuild the application without error. I only get this error when I try to Publish.

Regarding #2, I looked in my SDK\v3.5\Bin directory and indeed the signtool was not there. In fact I only had 3 files (genasm.exe, genasm.exe.config, and hidpi.res). I copied the signtool.exe from the Visual Studio 2005, (file dated 10/26/2006), but I still get the same error saying it can not find the file.

Any guidance would be appreciated.
