So just had IT give me a new ssd. installed same version of java which works on other computer. can open projects no problem. Designer won’t launch though. I see the Java loading window open then it goes away. no errors or any indication anything went wrong.
You almost certainly have 32-bit Java installed, but the designer is asking for more than 1.5gB memory; when it tries to allocate the extra memory, it fails, which is why you see the Java splash and then nothing else.
Look at the launcher’s log file to find the final java command it attempted to run. Copy that and paste it into a terminal window to run that way. That will give you log output.
Try simply disabling the x86 version entirely?
I’m not familiar with whatever control panel you’re looking at there, but this is an issue that came up all the time when I worked in support.
In v7.8.5? I’m not sure. Start by looking in the folder you are running the launcher from. Then look in .ignition. It will have a modified timestamp from your last attempt.
