Problems with office automation in asp.net. I can use alternatives such as open-office, if I knew how

Question

I have a ASP.NET 2.0 web application that should upload a ppt file and then extract its slides to images. For that I have imported office.dll and Microsoft.Office.Interop.Po

Answer 1

I might be wrong, started looking into a similar thing recently. But you should not need office installed on a machine to create or edit 2007+ office files. They are basically zip files with a different extention. If you rename it to .zip you should see all the files and be able to edit them directly.

It can then be unzipped and all the files are there for you. You can create new files in a similar fashion
