I just downloaded and installed the game, but when I start it, the launcher arrives at 100%, simply closes and does not open anything else, does anyone have a solution?
Try running client or patcher
as admin, hope this works for you!
check on task manager if the ToS_Client is running…
it takes long to load on low spec compu…
if nothing is running, try verifying local cache for the game on steam…
am sure if you Search 
around the forum you might find a better solution…
verify game on steam
