You have to find out why this fails...
I don't know how we can help with this problem.
Probably the mt.exe is not in the PATH?

BlueHazzard:
what if you call this

--- Code: ---mt.exe /nologo /manifest "bin\Release\example_mic_dyn.dll.manifest" /outputresource:"bin\Release\example_mic_dyn.dll";2
--- End code ---
from a command line inside your project folder?
