The Access Guarantee option makes it possible to re-download software you have ordered and view any product key(s) issued with it for 31 days after you order the software (or 24 months, if you opt for the Extended Access Guarantee). This can be very useful if you ever have to reinstall a piece of software you have ordered.
In most cases you will receive the Basic Access Guarantee free of charge with your order and will have the option of upgrading to the Extended Access Guarantee during the checkout process. For details about each option, see: What is the difference between Basic Access Guarantee and Extended Access Guarantee?.
The Access Guarantee option does not extend the duration of your license. If you purchased a six- or twelve-month rental or trial software, your license will still expire in the expected timeframe.
The Access Guarantee option provides access only to the download links and keys issued with your order. It does not mean that you will be able to download and install the software an unlimited number of times using the same key.
The Access Guarantee option is not available on all WebStores.
