V1.5 of the ACDI will work freely with Avolites Visualiser, although upon startup ACDI will ask you to register with Avolites. To use ACDI, simply click on "Cancel.
To use the ACDI with third-party visualiser programs, a License key is required. This can be purchased from the Avolites Shop.
So i downloaded ACDI but it is still requesting for a license key, but i understand it was free to use with the avolites visualiser? So am i doing something wrong or do you need a license key for that too?
