When I try to export the client install package for windows from the SEPM (Symantec Endpoint Protection Manager), nothing happens. I don’t get a prompt or a window to continue with the export.
This can occur if you import domain settings from a different version of SEPM. Importing SEPM domain settings is not supported between different versions.
Refer to the following article for more information regarding SEPM domain export/import.
Create a new domain and delete the other one.
