I seem to be having problems with using dual instances of SGP to run a piggy back scenario. I have a Moravian 16200 on the main scope and an ASI 1600MM Cool on the piggy back scope. I also run two robofocusers. I can’t seem to even get the program to launch for the second instance. This makes me wonder if this can be done. I have seen others posting that they can run dual instances and have even seen the developer remark that it can be done on other posts but for some reason I can’t even get the program to start up. Any settings I have to watch out for that would crash the second launch of SGP on the same computer? I am not even sure I can get a log on the failed launch. Maybe I can post a link to the screen shot? I guess first thing is are there any settings I need to check?
