I cannot create an instance of the 'Excel.Application' on my PC when requesting the html page from our intranet server which is running IIS. However, when I request the *EXACT* same page from the site on my PC (using PWS) it works!! Why is this?? Can someone please help.<BR>Also, not everyone has this problem. All the PCs have excel installed on them, and they are all the same version (v5). I've even written a small VB exe to simulate the same code and this works fine.<BR>Does anyone have any ideas on this?
