Synthera DocsThe Ancient ARC Raiders instructions describe a first-launch update that may close the loader and randomize its filename.
Keep the game closed.
Wait for the update to finish.
Open the dedicated folder where you saved the loader.
Locate and reopen the updated launcher.
Continue with the Installation Guide.
Closing after a completed Load operation is also part of the described launch process: start the game only after preparation finishes.
If the loader closes repeatedly before login, shows an error, or disappears from its folder, contact Synthera Support. Do not assume every unexpected closure is a successful update.
