In previous post "IE8 Opened a Blank Page with Hyperlinks in Office 2007 from CD Optical Drive", HKEY_LOCAL_MACHINE...\SOFTWARE\Microsoft\Office\9.0\Common\Internet must be present for registry editing for ForceShellExecute .
In the event if HKEY_LOCAL_MACHINE...\SOFTWARE\Microsoft\Office\9.0\ … is not present in the Registry, will need to add the relevant Registry Key.
1. HKEY_LOCAL_MACHINE...\SOFTWARE\Microsoft\Office\9.0\... not available.
2. Click on “HKEY_LOCAL_MACHINE...\SOFTWARE\Microsoft\Office” > Right Click > New > Key
3. Rename the Registry Key folder name to 9.0
4. Create sub folder Key in the HKEY_LOCAL_MACHINE ….\Office\9.0 to
HKEY_LOCAL_MACHINE ….\Office\9.0\Common\Internet
5. In the HKEY_LOCAL_MACHINE ….\Office\9.0\Common\Internet, select DWORD (32-bit) Value
6. Add a new DWORD Name value at that Key = ForceShellExecute and adding a new DATA VALUE = 1
