To be fair, I don't think he did.
He said elsewhere that he and a friend had bought the aircraft and that while his friend's installation worked, his did not.

It must be very difficult for developers in these circumstances, I suppose a model can only be made to fit a standard installation of FSX.

Given firstly the vast number of addons which make changes and secondly the apparent willingness of FSX users to ceaselessly tinker with the installation it is hardly suprising that a given aircraft model will work for some and not others.

The solutions offered here and elsewhere do not seem to have been effective in this case, assuming as one must, that they were ever applied correctly.

It seems that whether his installation of the 737 can be made to work or not is no longer relevant.

Nick.
