Inno Setup ignoring Registry Redirection?

Question

I am running a setup on a 64-bit Windows 7 system. The script's (one that I've "inherited" and maintain these days) [Setup] section does not contain the ArchitecturesInstallIn64BitMode directive.

Per the docs :

• [Registry] writes to the 32-bit view by default.
• The Uninstall key is created in the 32-bit view of the registry.

This is my [Registry] section:

[Registry]
Root: HKCU; Subkey: "Software\{code:GetRegistryName}"; Flags: deletekey
Root: HKCU; Subkey: "Software\{code:GetRegistryName}"; Flags: uninsdeletekeyifempty
Root: HKCU; Subkey: "Software\{code:GetRegistryName}"; ValueType: string; ValueName: "InstallPath"; ValueData: "{app}"; Flags: uninsdeletekey
Root: HKCU; Subkey: "Software\{code:GetRegistryName}"; ValueType: string; ValueName: "CurrentVersion"; ValueData: "{code:GetVersion}"; Flags: uninsdeletekey

...and yet, all of the keys land in the 64-bit part of the Registry - that is, nothing goes under Wow6432Node , as I would expect. Here is my Registry view (with some light editing):

and:

My issue here seems to be the opposite of every other one I've found on Stackoverflow, where one complains about "missing keys", that were in fact under Wow6432Node .

WOW64 registry redirection mostly applies to keys under HKLM and HKCR. Only COM related keys under HKCU\\Software\\Classes are redirected/reflected. See MSDN for details: Registry Keys Affected by WOW64 .
