RegGetValue apparently isn't available in XP SP2. I tried and got an error. MSDN implied it wasn't available.

Example usage to get versions of browsers:

GetRegString( HKEY_LOCAL_MACHINE, "SOFTWARE\\Microsoft\\Internet Explorer", "Version" );

GetRegString( HKEY_LOCAL_MACHINE, "Software\\Mozilla\\Mozilla Firefox", "CurrentVersion" );

                                

                                                            

                                    

                                        

                                        Initial Title
                                        

                                    

                                    
Get a Registry string value as a CString, MFC. Examples to get version of browsers.
