We want to thank you for your patience while we worked to address this issue and we are pleased to announce that we have just released our newest, most powerful version of Camtasia yet. This Camtasia release is now 64-bit and should help on addressing most of the memory issues. However, you'd need to have a 64-bit OS to install the latest release. The full system requirements can be found here. You can buy/upgrade Camtasia here or download the trial here.
