<h4>Basic concepts</h4><p><u>The installed version</u> is the version of the add-on, that is currently installed on your store.</p><p><u>The available version</u> is the latest version of the add-on, that is available for you to install and/or update within the prepaid subscription for updates. For example, for the add-on there are versions v2.0 from February 15, 2019 and v2.1 from March 2, 2019 and your subscription to the add-on updates ended on March 1, 2019, then the latest available version for you will be version v2.0 from 15 February 2019. To receive version v2.1 of March 2, 2019, it is necessary to renew the subscription period.</p><p><u>The actual version</u> is the latest version of the add-on at the moment. We recommend you always update to the actual version, which contains fixed bugs and new useful functionality.</p><p><u>The add-on is not available for your store</u> — it is possible, the version of your CS-Cart does not correspond to the minimum acceptable version for the add-on. For example, the YoupiTheme is available only for CS-Cart 4.7.x and more.</p><br><h4>Installation process</h4><p>The installation of the add-on has never been so simple as it is now. After purchasing AlexBranding add-ons and installing <b>AB: Add-ons Manager</b> you can install the latest version of the add-on in one click, without any visits to the personal cabinet in the store, order search, downloading of archives, etc.</p><br><h4>Upgrade process</h4><p>Add-ons updating goes via CS-Cart <b>Upgrade Center</b>. If there is no update available in the CS-Cart Upgrade Center, the update is performed by Deinstallation the old version of the add-on and Installing the new version</p><br><h4>Cache</h4><p>After installing and/or updating, you must reset CS-Cart cache. See CS-Cart <a target='_blank' href='https://docs.cs-cart.com/4.7.x/developer_guide/getting_started/cache_clearing.html'>documentation</a> for more details.</p>
