You can get the program here:
With the new version, the requirements have changed a bit. Although you might as well try running it before installing the .net client profile. It needs:
- .NET Framework 4 Client Profile
- Photoshop CS2*, CS3, CS4, CS5, CS5.1, CS6, CC
There isn't a setup, just run "Typesetterer.exe" to get started. The other included application, "Tooler.exe", allows you to quickly use the text styling features without need for a script and psds.
