I've attempted an upgrade of version 3.1.06 to 4.1.12 from a system install area, however whenever I attempt to start the GUI I receive the message
'The ordinal 6905 could not be located in in the dynamic link library MFC42.DLL.' I have one MFC42.DLL file located in the winnt/system32 folder which is version 4.21.7303, there is also a file named MFC42u.dll here. I have a couple of other files named MFC42.DLL on the system but these are used by other applications, any idea why it's failing? Marc.
