Thank you for your enquiry. Yes, to be able to load the created stationery into a GroupWise mail message using the Stationery solution, Formativ Runtime 2.0 and the Stationery Applet needs to be installed on the target user’s workstation. You also need to copy your stationery HTML file (and any images) to the Stationery location on the other users’ workstations. To find where the Stationery files are located, see the Settings… option on the main Stationery dialog.
Formativ Runtime 2.0 is the core framework required to execute Formativ Applet solutions (such as Stationery, Templates), similar to the way you need JAVA installed to execute JAVA based solutions or the Microsoft .NET Framework to run .NET based solutions.
I hope this answers your question.
