Office 2003 and 2007 Office documents open read-only in Internet Explorer via SharePoint

After searching the web I found workaround that should workhttp://support.microsoft.com/?kbid=870853. According this article:

  1. Quit all running Office 2003/07 programs.
  2. Open register (regedit.exe)
  3. Locate and then right-click the following registry subkey: HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Common\Internet
  4. Point to New, and then click DWORD Value.
  5. Type OpenDocumentsReadWriteWhileBrowsing, and then press ENTER.
  6. Right-click OpenDocumentsReadWriteWhileBrowsing, and then click Modify.
  7. In the Value data box, type 1, and then click OK.
  8. On the File menu, click Exit to quit Registry Editor.
