Hi, Umberto,
I have done as you suggested.
1) Disabled ALL of Windows Defender. (no other anti-virus software installed)
2) Allowed coulal.exe through my firewall.
3) Completly removed/un-installed any trace of your Addon Manager.
4) Downloaded a fresh/latest copy of your Addon Manager.
5) Installed your Addon Manager version 4.0.0.8.
6) Started up P3Dv4.1 flightsim
7) Received ERROR message as shown below.
Have also Attached a digital Signature of Coual.exe for your attention.
p.s Have also removed P3d4.1 from system and re-installed it, with no other additional software but I am still receiving the same error message. Is there anything else I can try,.... help you with.
Regards
