Inno Setup: RegValueExists does not return true, trying to check Registry Key

I want to show Components based on the existence of a registry key:

[Components]
Name: "MyProgram"; Description: "MyProgram"; Check: RegistryCheck

This is the corresponding function:

function RegistryCheck: Boolean;
  begin
    Result := RegValueExists(HKEY_LOCAL_MACHINE, 'SOFTWARE\Bricsys', 'RegisteredOwner')    
  end;

I don't know what's the mistake, the installed program which has to be checked is x64, running IS on a x64 machine.

Key:

Rootkey: HKEY_LOCAL_MACHINE
Name: RegisteredOwner
Type: REG_SZ
Data: User

If you are trying to install on a 64bit OS you may be looking in the wrong RootKey.

Try using the following instead...

RegValueExists(HKLM64, 'SOFTWARE\Bricsys', 'RegisteredOwner')
