How do I get a registry value in Inno Setup when the value only uses the default name?
Just leave the SubKeyName empty, like so:
[Code]function InitializeSetup(): Boolean;var V: string;begin if RegQueryStringValue(HKLM, 'SOFTWARE\Google\Google Sketchup 6', '', V) then MsgBox('Value is "' + V + '"', mbInformation, MB_OK); Result := TRUE;end;The matching documentation for the underlying API call is for RegQueryValueEx(), which states:
The name of the registry value.
If lpValueName is NULL or an empty string, "", the function retrieves the type and data for the key's unnamed or default value, if any.
