cannot download for sophos installater package

Hi Nyein Chan Zaw ,

Thanks for reaching out to the Sophos Community Forum. 

Can you share with us the below details:

• what license you have in your Sophos central dashboard?
• What package are you trying to download?
• Is it for the server or for the endpoint client? 
• Is this the first time you're trying to download the endpoint package or was this working before? 

This article describes the options available to install Sophos Central Endpoint and Server software.
