You need design software to use our products. Vector Packs should be used with Adobe Illustrator. We cannot guarantee compatibility for Corel users. The apparel templates require Adobe Photoshop CS or newer. If you do not have Photoshop and would like to mockup your designs then check out our other site, Mockup Everything which is a web based app that you can use for $12/month after your free 7 day trial.
Motion Packs are best used with Adobe After Effects.
