After installing office 2010, I can't upload files anymore using wss 3.0. I was able to add new documents in my Portal (developed on WSS 3.0) when I had office 2007 on my machine. After installing Office 2010, a new activex control poped up and I installed it as usual and after that I am not in control anymore.

Hi, Thanks to share your post. For the issue, please first uninstall the pop-ups that you have installed in the internet explorer->tools-> manage add-ons. Disable the pop-up. Or you should use the C# to program this to upload the file: http://msdn.microsoft.com/en-us/library/ms454491.aspx. http://geek.hubkey.com/2007/11/upload-file-to-sharepoint-document.html. Hope this could help you! Leo
