Product Version:

I have a Windows XP Professional machine with 2 clients installed (8.1.7 and 9.2.0).
I execute the Home Selector and switch between the homes - Nothing Happens !
I am also unable to query registry values from the HKLM\Software\Oracle\ALL_HOMES, HKLM\Software\Oracle\Home0 and the HKLM\Software\Oracle\Home1 nodes.
