getting started with Jenkins. Learning as fast as I can! Trying to setup msbuild in the tools config. i have this:

Then I have a job set up to do a build using an explicit setting and another using the msbuild from above:

When I run this job, the first build works but the second one fails:

I figure its just me being a noob. Why does Jenkins find msbuild.exe in the first build step but not the second? What do I need to change?
