Dear Chimera Users My name is Sergio Garay, I have installed chimera-1.15-win64.exe on Windows 10pro 64bit. But when the program starts to run, the system gives me the following error message and the program closes: chimera exited abnormally; the exit code was: -1073731819. use the -- debug command line option for the full error message I tried installing the two previous versions of the program, with the same result. My PC has a Radeon RX 580 series videocard, and the system uses a WDDM 2.7 video controller. Could you give me any advice on how to fix this problem?
