Failed to start launcher: invalid argument

[PhoenixSSJ]

I have tried to update this, but in the end I get "Failed to start the launcher: invalid argument" Does it happen to someone else? Do you know how to fix it? I need help please

Are you on windows 7?

[PhoenixSSJ]

No, im in windows 8.1

[HannesC]

There's your issue. Upgrade to win10, older OS'es aren't supported

[Zenitsu]

Is posible to modificate the code of the game to fix it?

[Xerxes]

There is nothing broken so nothing needs to be fixed.
Not even Microsoft is giving you support for those OSes anymore, not even for a lot of money.

Zenitsu windows 10 is free dunno why you wouldn't upgrade to it
