Where to download SDE version 4.0

We have a Professional floating license for SDE 4.0. I am not ready to upgrade to 4.1 because I am not sure I want to pay for the upgrade. I need to install SDE 4.0 on my PC. But the download page only has version 4.1 available. where can I download version 4.0?

You can always login to the Customer Service Center (https://cs.visual-paradigm.com) and select the Software tab to download the VP Suite installer which fit for your licenses. If you are not sure your login ID, please send an email to sales@visual-paradigm.com and we will help you to check it out.

Best regards,
