While upgrading from Windows XP or Vista to Windows 7, youmay face
QuickBooksPrinter not activated Error code 20 . This error happens becausethe ‘new operating system’ puts out the Hkey_ Current_config\ software key in
the registry settings. In other words, the entries found on the key are not
updated when you upgrade the Operating system. In some applications, the exact
key is used to store the internal settings that lead them to fail the update.
If you are a QuickBooks user and have upgraded to Windows 7,there is a good chance you can face this issue. This app uses
‘Hkey_current_config\software’ key to store the internal settings, and because
the registry key is not updated there is a definite chance that the app will
not work correctly.
