Has it happened to you that you have activated the trial mode of a new software to get a first impression, but then had no time or no suitable project for a detailed test? If you have time or a project, the trial period is expired.
That can not happen to you at RedCrab anymore! You can request an activation code on a daily basis if you need one. Until further notice the number of activations is not limited.
Users who only rarely need a math software and therefore the purchase is uneconomical, can now access the full range of functions when needed.
