it doesn't work for me, since I activated the passenger box it has broken all the libraries as I said, why would I lie to you? please, what is the solution?
Your firewall or antivirus might have blocked the installer from being able to update itself when it starts. Be sure you turn off any firewall and you have the whole Addon Manager folder added to the Antivirus EXCLUSIONS, then start the installer again.
Also, try the Offline installer, which at least might not be affected by firewall issues or network issues.
ok, my liveries are now fixed and working, but now the passengers were pink and checkered, reading the manual page 10 and following its instructions I opened again the fsdt installer, I have gone to configuration to get the new liveries but even though I have disabled antivirus and firewall and adding it to exceptions in my antivirus I get this popup " the specified file could not be encrypted" (see attached image) many times for each of the liveries, and broke all my fenix liveries again... im lost again, can you help me?
