I downloaded and installed the latest ISX Designer update this morning. Version 10.3._20180917x86_64
Now when I launch from the desktop the application opens the sign-on page and then quickly disappears. I am running Windows 10 64bit. I uninstalled and re-installed again. I have restarted the PC multiple times also.
I also tried to uninstall and then install an older version. Same issue.
I am at a loss.
