I had Toad for Oracle 12.5.1.1 in my machine. After reboot it was not launching. Software support uninstalled 12.5.1.1 and installed 13.0.0.80. I have the same issue of stuck with Setting global options and application is not launching. I tried with run as administrator and did not work. We did several reboot of my machine.
Please note that all other software are working fine. I have Toad for DB2 6.1 and its working fine.
Thanks in advance for any ideas to get this issue resolved.
