FSX, FSX-Steam, P3D v.4.xx+

Some time ago, we had "EZCA Simconnect bug". The reason - the code transition  to windows11.  We released EZsc_loader patch but this  patch did not work correctly.
We fixed the simconnect issue for windows 11 users. Those who bought the product after February 1 already have all the necessary fixes in the installer. But there are users who upgrade from win10 to win11 -  you need to download the latest version patch here:

EZCA simconnect patch for win 11...

Run this patch, select your EZCA version, wait for the download to complete. After that run ezca configure tool - for advanced users , select simconnect version 10.0.61259.0 . Close the configurator, enjoy your flights.
