Good Day Umberto. Today I googled VC++ updates and found a very good step by step how to from MS. I uninstalled all VC++ from my PC. I used their most current updates and SP1 for all VC++ 2008,2010,2012,2013,2015, both x86 and x64. Simple and easy to do. Reboot PC. I then uninstalled all Virtuali FSDT programs again including SODE. Reboot PC. I used your website to install just GSX and KORD with my antivirus OFF. Also ran the most current addon manager live update from your site. Tested this with FSX running a MS boeing 737 at KORD. Still unable to get out of Trial mode, and still no COUALT or GSX showing up under addon menu.
I see other users having this problem on the forum posts. And I definitely excluded the ADDON manager folder in AV from Trend Micron.
Could this be a error in the Coualtaddons.ini file in the c:\users\wayne\appdata\roeming\virtuali file. I can send you what I see in this file to see if all the parameters are set correctly. I am not a programmer and don't know what should say coualt = disable or enable or whatever.
I hope we can solve this issue for me and others.
