ERROR: Unable to update the dependencies of the project.

Today, out of blue, my vs2010 setup project is not working, keep telling me errors like:

I searched online, it is said the error is due to "VS2010 QFE: Setup project compilation fails with command line" and find this hotfix from microsoft to fix the problem:
