All flipcharts created in ActivStudio or ActivPrimary will have the file extension .flp. ActivInspire uses the file extension .flipchart to save flipcharts. If your computer has ActivStudio or ActivPrimary installed as well as ActivInspire, when you open it, it may still open in ActivStudio or ActivPrimary instead of ActivInspire.
Open ActivInspire, click the File menu and select Settings. In the bottom left corner, click Restore File Associations.
Right click on a .flp file, and select Get Info.
In the Open With section, click the drop down and select Other.
Browse to Applications | Promethean | Activsoftware Inspire and select Inspire. In the same window, check the Always Open With box, and click Add.
