this is my first post here so my apologies if this is not the correct Sub-Forum.

I've a thread with VBA code accessing the registry.
This code, getting info from the registry in HKEY_LOCAL_MACHINE perfectly work with XP and VISTA, but does not return any results on a WIN8-64 box, dispte the searched key may be viewed using REGEDIT. (The condition ERROR_NO_MORE_ITEMS is directly met)

I assume the CONST HKEY_LOCAL_MACHINE should be different for WIN8-64, at least, but i don't know where to find the correct values.

Thank you in advance for any help.
