Trouble downloading or installing?

If a server fails or is slow, download from another one: they all deliver the same file.
Windows may warn about an unknown publisher. Click "More info" and then "Run anyway".
If your antivirus blocks the game, add the install folder to its exceptions and open the launcher again.
On Windows 11 with Smart App Control turned on, the launcher may be blocked as "publisher not verified". The launcher's digital signature is on its way. Until then, you can turn that control off in Windows Security › App & browser control › Smart App Control (Windows warns it cannot be turned back on without reinstalling), or wait for the signed version.
