II've managed to get EZCA start up. However my first problem was that it wouldn't show up in the Addon entry in the FSX menu. This was due to Simconnect not working properly. However if you go to directory - SteamApps/common/FSX/SDK/Core Utilities Kit/SimconnectSDK/LegacyInterfaces you will find three directories. I'm not sure which is exactly the correct one but I used FSX-SP1. If you go into any of those three you will see a SimConnect.msi. This will setup SimConnect and Ezca will appear in the Addon entry in the FSX menu.
After that you can get EZCA showing up and you can see the studio open up. However I have a problem and that is that although it the Ezca studio appears I cannot set up a key/button to execute the specific camera. In fact I can't get it to work from the studio. I would be grateful if anyone has sorted this problem could post it. One problem is that it won't accept button or key entries for a camera. Without Ezca using FSX is a pain.
I am not a Steam afficianado but at a price of £3.99 it looked like a good bet, especially as it is almost impossible to get a new FSX disk these days, certainly not at a reasonable cost.(I will have to back up my FSX disks! As a side issue is it possible to activate a new FSX installation now? Does the online activation still work?).
So far I have been able to get some of my exisiting aircraft copied across and some scenery and the aircraft seemed to work ok. Scenery i'm not quite sure about.
My general impression is that FSX:SE is not a great idea in itself. If FSX is developed further,, and it is easy and free(!) for the updates, then it might be worth it. (I have installed it on a laptop on a completely separate machine from my main FSX installation. I wouldn't want to take the risk of damaging my main FSX setup.) However, FSX:SE without addons is basic and takes us back to the beginning, basic scenery and basic aircraft. i will keep it on the laptop for when I'm away from my main computer but i doubt if I will use it much. Certainly until i can get EZCA working.
