So should I download the universal installer then the offline installer??
Always run the Online update first, then the Offline installer but ONLY if you suspect your cloudflare node is not up to date, the instructions in the Sticky thread of Offline installer explains what you need to look for to recognize this is your case.
Also I’ve tried the log followed instructions but nothing came back after restarting the engine.
With "after restarting the engine", you mean it looks the program is running ( its icon appears in the Windows Tray bar notification area ), if you don't see a log, you must have done something wrong enabling the log. The Sticky thread about "How to report an error", contains a pre-made Couatl_MSFS.INI file that is surely correct, so you only need to place it in the correct folder ( %APPDATA%\Virtuali ) and a log will be generated.
If, instead, the Couatl engine hasn't even started ( no icon in the tray bar ), that would explain why you don't have a log, and this problem is almost invariably caused by the antivirus, so you need to do as follows:
- Configure the antivirus and add the whole "Addon Manager" folder to the Antivirus EXCLUSIONS
- Run the FSDT Live Update again.
