I was able to register and login just fine, kind of shambled around the game for a bit, and then closed the game. But now, when I try to play, I get the message "Failed to move update files. Please try restarting the game."

I've already tried restarting my computer. What's going on here?

yeah getting the same problem now

I managed to fix it by running the shortcut "as an administrator".

I managed to repair it by clicking the installer again and selecting repair option. Restart the computer after that.

@Sunnova
I tried that and it still gave me the same response.

@Thony
Ah, I had to restart after repairs, got it. I wound up uninstalling and reinstalling everything; I have no problems now. Thank you!

I also had a problem with getting the game to launch from the shortcut. So my solution was to run the game application from where I installed it. Hope this Helped.

I get this problem but solved...here some solution

Solution for this one :
1. run the game normally, if not worked ----> see No.2
2. run as administrator , if not worked ----> see No.3
3. restart the PC, the re-run it , if not worked ----> see No.4
4. after restarting the PC..... u should run the game as "run as administrator"

it's no need to re-install it...
coz it's just a bug when computer move the update files and not able to,
or computer dont have any permittion to copy the update file. (after restarting it should fix this problem)

tried all the tips..sad to say, its still failed to update..guess its time to drop the game..

I thought it was a corrupt file..but thanks!
