Here you can get Scriptly for free. The download is available in two versions, which only differ in the way of their installation (see below for more details).
The current version of Scriptly is 0.8.95.6, which was released at: 2010-11-25
Standard version, recommended for use with Windows Vista/7 (and upper) and especially in multi-user environments
Compact version, recommended for advanced users and for installation on an USB stick (data will be saved in program folder)
Please note, that I cannot (and will not) guarantee, that the program is working completely appropriate. The application is not under active development anymore, and I can't say if or when a new version will be released. I also cannot guarantee to give support in case of problems, questions, etc.
