Yes - you can interrupt the update process and resume downloading updates at a later date without too much chance of errors.
Concerned about the sheer number of currently installed TRS19 Platinum assets apparently needing updates according to your listed returns, CitMusJoe.
Did you have a large number of additional routes and sessions carried over from previous TRS19 versions in your UserData folder (in addition to the built-in Platinum selection)?
When I started TRS19_100240 today there popped up a window with a bunch of routes Locos etc. AFAIK I've already installed them some time ago.
Seems to be some stuff I've purchased for TANE too.
Before beginning to calculate what's better to do in this situation I aborted all actions and shutdown TRS19. BTW I'm talking about build 100240 (=no SP1).
At the moment I' wanted to count the number of routes installed. Now, past aborting, I can see some new routes/sessions inside TRS19 (no SP1).
Some routes were carried over from TANE, to answer your question. Now in TRS19_100240, after clicking onto [DRIVER / SURVEYOR] I counted 27 yellow marked routes. All other routes are marked white at the bottom line of the the thumbnail preview window.
BTW now I could see some foreign routes that I've never had before all my applied database actions, e.g. Russian routes etc. I'll delete them all here in the hope this makes sence and will eventual try again to repair...
Should I on my next attempt first download that huge routes (this downloads alone took about 2 hours) or skip it and do a cleanup first? I'm unsure what's best to do now
If I get this one a days done I can continue to apply all for build 105096 (SP1).
