Do I need to register MusiCAD?
probably not: you may use the software without registration/license as long as you like;
Why should I register MusiCAD?
probably you want to share your files with others which is not possible without a valid license...
you just bought a new computer and want to edit or print a piece of music you saved earlier in evaluation mode...
Obtaining a license involves the following actions:
Complete the registration form in [Help|Registration] and use the e-mail button;
Double click the attachment from our e-mail that we will send as soon as we have received both payment and registration form (usually next business day);
Your evaluation-copy is now a registered one without the limitations of the evaluation/demo-mode.
