RQM Copy Utility Setup

Hello team RQM;

I am trying to run RQM Copy Utility but I cannot run it.

I have performed the following steps:

1.- Download the RQM-Extras-RQMCopyUtil-3.0.1.5.zip them unzip and save in C:\RQMCopyUtil

2.- I obtained the located Java Runtime Environment JRE path (JRE7): C: \ Program Files (x86) \ Java \ jre7

3.- from CMD.exe I executed the following command:

C: \ RQMCopyUtil> "C: \ Program Files (x86) \ Java \ jre7 \ bin java-jar RQMCopyUtility.jar -help"

But I get this: is not Recognized as an internal or external command,
operable program or batch file.

Could you tell me what I did wrong step?

Thanks in advance.
