Windows 7 environment variable not working in path

Question

I am trying to set up some path using environment variable. I added an environment variable \"MAVEN_HOME\" with the value \"C:\\maven\". Then in the path I added \"%MAVEN_HO

Answer 1

Copy the value of path to notepad and check if this corresponds with the echo %path% in terminal window and make changes if needed. Then delete the old path value and paste the notepad value back in. I assume some invisible character entered there by some installation corrupted the path value.
