For this error, the solutions in this post seem to help with most cases:
@ddadain You may want to have a look here, too.
I keep getting that Update Fail message, windows 10. Also restarting seems to help . . .sometimes. @STAFF_Ines
I am still getting the updater. Updater_loader.exe (927) fail message. tried all the suggested solution this post have provided. Still fail⌠Please advise.
Hi, @STAFF_Ines Iâm still getting the âUpdate Fail, Please Restartâ Error. Iâm also running windows 10.
Didnât work for me. Also everytime I verify game cache after updater fail to update game is re-downloading 3-6 files, number seems to vary each time. I recon that your update server in KR have issues on its end.
I bet today wont be fixed either.
Yes I am getting this message too, windows 10 here
Cant log on to SEA sever but others are ok
This is for people who failed to unpack patch. We are unable to get past launcher because of
Edit:
I have literally tried every possible step that is out there, and that i can think of. So This is not our end fault, but IMCâs side. Either server went on full derp mode between 3 AM GMT +2 and 7 AM GMT +2. That is the time gap where something happened. And problem is starting when our client is trying to reach server side updater stuff
Each time after update fail, and when i try to verify game cache, i get this validation. So seems like our updater is trying to download corrupt files each and every time.
tl;dr
Disabling DLC doesnât help.
Reinstalling doesnât help.
Launching as Administrator doesnât help.
Addind to exeption firewall/av/any kind of program that is trying to protect my pc from ToS doensât help.
Updating drivers have nothing to do with this issue.
Windows 10 shouldnât be at fault here, because there wasnât any update for last 10 hours.
After enabling DLC again, and trying to launch ToS again, it download the launcher again each and every time (even if while DLC was disabled i had the same error)
So yeah. I am sure thatâs where the problem is, This freshly enabled DLC and updated launcher because I enabled it and after i click play thereâs the same error that we all experienced already.
ps.
Already tried with other ppl âpatchâ folder, the one where DX10 is at.
I noticed that my game download Updater_Downloader and patcher.version (inside is number 8) files. So i guess thatâs where the problem is. @STAFF_Ines

Ok. An update from me. taking out founder pack from steam works.
Step by step guide if you are really lost.
open steam game library > locate TreeofSavior > under DLC untick Founderâs Pack > start Treeof Savior > it will patch again then Enjoy gaming!
When i unchecked the DLC, i can run launcher but can not connect to the server.
in case you havent read my post just above yours - your idea doesnt work for everyone, at very least not for me.

Okay, luckily i have 2 computers and the other works fine, then i fixed it.
Step 1: Delete patch folder at Steam\steamapps\common\TreeOfSavior\release
(not patch folder at Steam\steamapps\common\TreeOfSavior)
Step 2: Download this patch folder
https://drive.google.com/open?id=0B02LIk1BXe1yQUVPWUNYZEFibTQ
and extract into Steam\steamapps\common\TreeOfSavior\release
Step 3: It will be error âfailed to downloadâ then edit the file follow this Simple fix for âFailed to download pak filesâ errors
P/S: remember turn your DLC on
