After opening the windows registry i have done the following
Open Window’s registry by opening a Run window and entering regedit.
Navigate to HKEY_CURRENT_USER\Software\Mercury Interactive\QuickTest Professional\MicTest\ReservedObjects.
Create a new key (folder) named GlobalDictionary by right-clicking on the ReservedObjects key and selecting New -> Key.
Under the new key, create a String value named ProgID by right-clicking on GlobalDictionary and selecting New -> String Value.
Assign “Scripting.Dictionary” to the new ProgID string value by right-clicking on ProgID and selecting “Modify.”
If QTP window is already open you need to close and restart it.
Now to check whether dictionary object was installed successfully in registry, simple write GlobalDictionary. (don’t forget the dot) and you should see a drop-down containing all methods and properties associated with dictionary object.
After Doing this i am making use of GlobalDictionary but not sure about it.
I did wonder when you used the word 'registry' whether you were referring to the Windows Registry or to something like a library that you were calling a Registry.
I'll put my hands up now and admit this is outside my area of expertise.
