I've now timed it and it takes, on average 97 seconds for TC Pro platinum 2018 to start on my machine, from the click of the icon to the non-dismissible advertisement for TurboPDF. (which I read I can fix woohoo!) There is a similar delay the first time I try to open or save a file (not quite as long though). I have a core i7 with 16GB of RAM and CPU load is showing as being very modest. Wondering what the heck it is doing and if there is some way to make it start up in reasonable time?
