I got problems to upgrade compiler from Visual Fortran 5.0 A stardard to Compaq Visual Fortran Prof. edition 6.6 in Windows NT environment. Installing program is asking installation key but do not accept it. In announcement window is text ' this is installation from version 6.5', on the other hand in package is a text 'upgarde version, needs purchage Visual Fortran 5.x or 6.x.
We have two licence for 5.0 A but both old keys give the same error message.
What shall I do ?
