DEP - trying to make executables NON-DEP Compliant using msbuild and Team Build Project

Question

I am attempting to resolve a DEP issue by running editbin.exe /NXCOMPAT:NO in a TFS Team build project (instead of just the post build event). Primarily because we have to put the executable into an .msi for deployment.

Here is the code that I am using in the target:

$(VS90COMNTOOLS)....\VC\bin\editbin.exe $(SolutionRoot)..\Binaries\$(FlavorToBuild)\my.exe"

However, when the build project runs I am getting the follwoing result in the build log: msbuild error: 3079: ... "exited with code 128"

Does anyone know what "code 128" means? Note, when I execute the resultant commands (as found in the build log) within a cmd.exe window the commands run successfully.

Any thoughts or recommendations are greatly appreciated.
