Regenerate Anisette Data for iOS on Windows
Apple creates a folder on Windows where it stores the Anisette Data, which is used for the signing process of iOS apps.
If you receive an error in AltStore or AltServer about invalid Anisette Data, you might want to delete the folder and reconnect your device.
This will regenerate the contents of the folder.
The folder is located here:
It is worth mentioning that the folder contains invisible files.
They're invisible because Apple sets the file attributes to invisible.
When deleting the folder or files you might have to trust the computer when reconnecting your iDevice.
There's also a chance you have to use 2-factor authentication to do so.
The files are being used by Software like AltStore.
