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".
Thanks! I was experiencing a similar issue: when I clicked the XL button on a table, it would act like it would export to Excel, but if I had another Excel document already open, it would not appear. It was technically open because I could CTRL-F4 and close the document to return to the active Excel file, but it acted like Excel was disabled. Installing the plug-in fixed the issue!
