I open an application in Access Point using AJAX zero foot print. Then, I right click on a table and click on "send to excel". Another Internet explorer tab opens up and then I get the "HTTP 404 error page not found".
To start you do not need excel or a license for excel on the QVS server. Are you seeing any errors when you are trying to export the file? The excel files should be created in the default location of c:\ProgramData\QlikTech\QlikViewServer\Temp and you should be able to see them there.
