I guess maybe I did not explain my self, about the re-installation, that has been done already but, my questions id about this app, how did I get it in the 1st place and what is this for?
As I've said, you must do only what the message says: uninstall the previous version and then proceed with installing GSX, which will install it automatically. No need for you to search around. The newer version is INCLUDED with the GSX, which cannot proceed, until you uninstall the old version first.
Everytime I do replays in FSX for the FSDT sceneries, they are all gone!, They work just fine in simulation, but if I want to record a landing and start a replay then the airport goes dead, like if its just nothing there, barely the ground where the airport should be installed, any ideas as to why? Also How can I fix this?
This is a well known limitation of the FSX video recorder, and there's just nothing we can do about it: it doesn't record objects created programmatically, and this doesn't affect just FSDT sceneries, but every scenery that use Simobjects, and there are quite a few around now.
The only solution is to use other ways to record.
