Unfortunately we do not support downloading elsewhere but from the launcher.
If you still wish, you can use the google drive made by the community here: https://drive.google.com/drive/folders/1ReH4OpdnpVsFsDiVHxVHaD4glBjOgFDh and have the launcher to do file repair on top of it.
Maybe you can put someone inside your dev-support team to maintain an updated gdrive link who is much faater and then improve fast verify files. Cause lets be honest if you recommand only launcher it will not be confortable.
Can u please consider that suggestion?
