# Why is NextSeq 1000/2000 control software update not available from the Software Update menu?

Updating the software makes sure the system has the latest features and fixes. Software updates are bundled into a system suite, which includes the following software:

* NextSeq 1000/2000 control software
* NextSeq 1000/2000 recipes
* Universal Copy Service
* Real-Time Analysis

The system can be configured to download updates automatically or manually.

* **Automatic Updates** - Updates are automatically downloaded from BaseSpace Sequence Hub to install. This option requires an internet connection, but not a BaseSpace Sequence Hub account.
* **Manual Updates** - Updates are manually downloaded from the web, saved locally or to a portable drive, and installed from the saved location. This option does not require an internet connection for the instrument.

To enable/disable Automatic Updates - configure the Software Updates from the Settings Menu.

1. From the control software menu, select **Settings**.
2. Choose whether the system checks for software updates automatically:

* To check automatically, select the **Autocheck for software updates** checkbox.
* To check manually, deselect the **Autocheck for software updates** checkbox.

3. Select **Save**.

Systems configured for automatic updates display an alert when a software update is available. If an alert is not displayed one of the following may apply.

* System is operating under the most recent version of control software and no update is available. Verify against the [NextSeq 1000/2000 Software Downloads](https://support.illumina.com/sequencing/sequencing_instruments/nextseq-1000-2000/downloads.html) page for the most current version of control software available.
* The system is not connected to the internet, verify internet connection and try again.
* If currently logged in as ilmnadmin and update is not visible, verify ilmnadmin password is within expiration. Updates to the control software must be completed from the `ilmnadmin` account. This password requires update every 180 days, when prompted. If the `ilmnadmin` password is expired, the automatic download of the updated software suite cannot be completed. Update the `ilmnadmin` credential and retry.
