Hi virtuali and AthenaG! Thank you for your assistance!
However, both of your procedures don't work! I installed FSDT Installer from the site and I've turned off the antivirus!
Furthermore, an icon called ''Start Couatl for GSX MSFS'' appears at my desktop!
FSDT installer occupy all size of the screen! As you can see at the attachment!
When I click at GSX Pro it chashes ( nothing happens ). And when I click at the options at the bottom of the screen, nothing happens as well!
Thanks! Rogério.
