When I click on a hyperlink in a message IE doesnot launch, nothing happens at all. I have tried to re register the urlmon.dll file following insrtuctions from the microsoft website but that has not solved the problem. Can anyone out there suggest anything else?

Did you try the other .dll's?

• Urlmon.dll
• Mshtml.dll
• Actxprxy.dll
• Oleaut32.dll
• Shell32.dll
• Shdocvw.dll

Restart the computer to enable the changes to take effect.

If the problem is still not resolved, verify that the following registry values are present and correct:
HKLM\SOFTWARE\Classes\Interface\{00020400-0000-0000-C000-000000000046}
Name: (Default)
Value: IDispatch
HKLM\SOFTWARE\Classes\Interface\{00020400-0000-0000-C000-000000000046}\ProxyStubClsid
Name: (Default)
Value: {00020420-0000-0000-C000-000000000046}
HKLM\SOFTWARE\Classes\Interface\{00020400-0000-0000-C000-000000000046}\ProxyStubClsid32
Name: (Default)
Value: {00020420-0000-0000-C000-000000000046}
