1- TRC Link and RCSLInk are ready to use packed software that wont let us see exactly the assignments. I doubt that because same configuration worked with XPUIPC, there should be a problem with compatibility with MSFS 2020 only and FSUIPC7. Seems I am wrong and I should find the problem somewhere else
2- I will check the FSUIPC version tomorrow. I think is should be version 4. it was designed to work with FS2004 natively. I think FSUIPC installed part of TRC software packages. because I dont remember installing FSUIPC on that old PC before.
3- Can I see the changes made on client (via old panel) on the FSUIPC7 software on my server node log?
4- one silly question. I bought the valid licence for both FSUIPC7 and WideFS. but since it is already activated with trial license, I cant add my own serial key. should I run the installer again?
