Excel automation - URGENT HELP

I have created a web application in asp with excel charts generated by server-side automation. I generate the xls file on the server and send it to open directly in the client's browser...

Server.CreateObject("Excel.Application")...

Up to now, it seems to work properly, even so well-known these problems and considerations:

My doubt is about licensing:
- Is Excel server-side automation allowed or not (talking about license) ? I'm not sure about it.

Following Microsoft's article:
"Besides the technical problems, you must also consider the feasibility of such a design with respect to licensing. Current licensing guidelines prevent Office Applications from being used on a server to service client requests, unless those clients themselves have licensed copies of Office. Using server-side Automation to provide Office functionality to unlicensed workstations is not covered by the End User License Agreement (EULA).

Do I have the responsability about my web clients excel licensing ?

Searching on the web, I've found another way to generate excel charts: Office Web Components.
But OCW can't be used on web server (internet) according to Microsoft's license:

I'm lost.


Please, someone help me.

you can not network on the web or anything any microsoft application.

in a normal working enviroment, there would be a server, that holds MS office.

then every station is required to have a licence to use MS office, even tho it isent installed. but in your case, people are not actually using microsoft office, to make and create documents, so therefor a license wouldent be needed for each user, just as you dont need a licence to use access for web application.


but if what is delivered to the user is a excel document, then you need a licence..

as an example, you can use microsoft word with asp to check spelling of words in a search box, (like google spelling), but there is only one licence per domain name, as no microsoft word document is being made, and then available for download
