Help, please, I can't get cmd.exe to run it, it keeps saying file not found

It gives me: C:\Windows\System32

I've been adding:   \Java\jre7\bin\java.exe -cp Nxt.zip Nxt       or      \Program Files (x86)\Java\jre7\bin\java.exe -cp Nxt.zip Nxt

It keeps saying file not found.  The actual file location for java.exe is: C:\Program Files (x86)\Java\jre7\bin\java.exe

What am I doing wrong?
