Hello People,
i have look for it, and i believe the people where Conquer is craching, is because the start file of conquer,"conquer.exe" is still the multiclient, and cotools can not handle it correct, so here you have my suggestion what to do:
1) close all Client (games)
2) close COTools v6
3) Download the new patch setup of COTools

and install that first
3) download this Update

for COTools, and put this file into your game folder where olso cotools is installed
4) start 2020.exe file (this update overwrite the conquer.exe with the orginal file from TQ)
5) start COTools, and then start conquer with the button in cotools.
6) try again if it crached. if it crached feedback is welcome, to find out why it crached!!
I hope it is solved now, and im working on an multiclient that works with cotools!
Greets,
ZeRo
