I can't publish in 2008, I was previously using 2005 and it published just fine.

Error 2 An error occurred while signing: SignTool.exe not found.

I know there are tons of hits for a search on signtool.exe on google. The ones I've found involve copying the file to X,Y,Z locations and ensuring signtool matches up with your VS command prompt path.

When I run my start-> program files -> visual studio 2008 -> Visual Studio Tools -> Visual Studio Command prompt. and type signtool.exe it finds the file just fine.

I have Visual Studio 2005 professional edition, Visual studio 2008 profession edition, Visual studio 2005 SDK February 2007, just installed Visial Studio 2008 SDK1.1 to see if that would fix it, no luck.

I have copied signtool.exe to lots of places that were suggested on the google searches, it is now located at all of the following:

C:\Program Files\Visual Studio 2005 SDK\2007.02
C:\Program Files\Microsoft Visual Studio 9.0\Common7\Tools
C:\Program Files\Microsoft Visual Studio 9.0\VB\Bin
C:\WINNT\Microsoft.NET\Framework\v3.5
C:\Program Files\Microsoft SDKs\Windows\v6.0A\Bin
C:\Program Files\Microsoft Visual Studio 8\Common7\Tools\Bin
C:\Program Files\Microsoft Visual Studio 8\SDK\v2.0\Bin
C:\Program Files\Microsoft Visual Studio 9.0\SDK\v3.5\Bin
C:\Program Files\Microsoft Visual Studio 9.0\VB\Bin\1033
C:\Program Files\Visual Studio 2005 SDK\2007.02\VisualStudioIntegration\Tools\Bin

I'm on windows XP

2009-06-12 update I can only publish if I copy signtool.exe to the project folder I'm publishing now.
