To Uninstall CryptUp

Exit Windows Explorer.
Next select Uninstall CryptUp in the Start / Programs / CryptUp menu (or any program group you chose during set up).
Alternatively, you can open Windows Control Panel, click the Add/Remove Programs icon, select CryptUp and press the [ Remove ] button. This action is, in all respect, identical to CryptUp uninstall menu option.

Never delete CryptUp install folder and it's contents before executing the uninstall procedure. Elements would remain in the registry and, besides cluttering it, they may impair Windows.
