I just downloaded 2.14.3 and I install.
During the installation, two error messages appeared (I attached the capture of them) when trying to delete two files. No JTAlert was running on my PC when I made the installions of the newer version
My operating system is Windows 10 version 10.0.18362 build 18361.
To the messages that have appeared I have omitted.
After installation I have started the installed version and it seems to work normally.
