32-bit applications are de facto accessing Software/Wow6432Node/<target key>, but to them it appears as if they're accessing Software/<target key>. This is handled transparently by Windows. If you want to disable this, you need to create the TRegistry class with the KEY_WOW64_64KEY flag set, this way you'll access the real Software/<target key>. Same is true if you use RegCreateKeyEx(), RegOpenKeyEx() or RegDeleteKeyEx() directly.
