I want to display the word 2010 on an aspx page.
It is simply not possible.
If document conversion is not an option, you need to switch to using a desktop application in which you can embed a word in a regular form. Or use webdav in combination with a word extension or vbscript extension in the document itself to handle what you need.
Update
see Nancy's answer. It seems that there may be a way.
