We don't recommend that you download and use a SQLGate legacy version officially.
Please keep in mind that you should always use the latest version.
However, if you have a past 'perpetual license', you may have limited access to past versions.
Go to the page below, log in and download the latest version available for your purchase.
If you are not able to use it after the above process, please check the following points.
- whether the license key is entered for the corresponding product
- whether the maintenance period has expired
