Problem in installing GoldenGate Director on weblogic 12c

Question

hello friends,
we have a server with weblogic 12c and a basic domain namely "base_domain" on it.(i have no earlier experience about weblogic).its path is "D:\Oracle\Middleware_HOME\wlserver_12.1"
i can start its AdminServer and we can login to its console.
now i want to install GoldenGate Director Server.but in installing  process when i set Weblogic location it gives me error :
"Please Select a valid weblogic install Directory"
i tried all of these paths :
"D:\Oracle\Middleware_HOME\wlserver_12.1"
"D:\Oracle\Middleware_HOME"
"D:\Oracle"
but the error remains yet.
i installed weblogic on another machine but nothing changed.
another thin is that i checked all places that oracle documents tells that should be updated
i mean :
1 Update the registry.xml file in Weblogic home directory to point to the
correct WebLogic Server home directory.
2 Update all of the scripts under %WLS_SERVER_HOME%/server/bin and %WLS_
SERVER%/common/bin to point to the correct WebLogic Server home directory.
3 Update the .product.properties file under %WLS_SERVER_HOME% to point to the
correct WebLogic Server home directory.
1 & 2 are correct (i think) but i couldn't find third one "product.properties"
please help me.
Whats the problem?
weblogic Servers : Windows Server 2008 64-bit SP2  and Windows Seven Ultimate 64bit
Weblogic version : oepe-indigo-installer-12.1.1.0.1.201203120349-12.1.1-win32
GoldenGate Director : gg-director-serversetup_win_v11_1_1_1_0_001

You should specify the middle-ware home direction.
The error normally caused by the wrong version installed, which doesn’t have the correct registry.xml in MW_HOME. I met this problem in the past which is because I installed a dev version of WLS in zip file.
After I install the installable version( I think it is the same version you used: oepe-indigo-installer-12.1.1.0.1.201203120349-12.1.1-win32.exe of WLS, it works fine.
