VS2008 vs VS2005

[eatonqst]

I have just been forced to switch to VS2008 Professional from VS2005 Professional. Here is the problem:

Solution would biuld and publish under 2005.

Start it under debug, everything is OK, it runs fine just like 2005.

Solution will build in 2008. No Build Errors.

When I try to publish in 2008, I receive the following errors.
"Cannot Publish because project failed to build."
"An error occured while signing: Signtool.exe not found."

I have copied the signtool from the C:\Program Files\Microsoft
SDKs\Windows\v6.0\Bin directory to the C:\Program Files\Microsoft
SDKs\Windows\v6.0A\bin and C:\Program Files\Microsoft Visual Studio
9.0\SDK\v3.5\Bin directory.

Any help would be appreciated.
