The "Name" parameter is not supported by the "SetEnvironmentVariable" task

CUDA build failed on VS2013 using 2010 project setting. Verified the same build is successful with VS2010. Our dev environment is up to VS2013 lately but still keeps the projects in 2010 version.

========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

We use the standard CUDA setup and build files. Please help. THANKS.
