I just downloaded FurnitureLibraryEditor 1.7 on my Windows 7 64 bit computer and I have Java 7 (32 bit) installed. Whenever I try to launch it, Windows says it can't open it and asks to search for a service that can open it, which is strange because this is just a local java file.

SweetHome3D runs fine and so does Art Of Illusion.

So, I did some looking around and I tried these (without success):

C:\Users\username>java -Dcom.eteks.sweethome3d.no3D=true -jar b:\FurnitureLibraryEditor-1.7.jar
the result:
'java' is not recognized as an internal or external command,
operable program or batch file.

Tried again:

C:\Users\username>java -jar B:\FurnitureLibraryEditor-1.7.jar
the result:
'java' is not recognized as an internal or external command,
operable program or batch file.

So, you see, Windows is not recognizing the command, java.
Can you help?
