I'd like to bump this up for response from the Softmaker Team.
I can understand it being an OLE issue if I was embedding one application within another Softmaker application ie a Planmaker document within Textmaker, however the issues described involve just jumping from one Softmaker application to another via the inbuilt buttons, and getting scripts to work within an application. This shouldn't involve OLE as all the applications reside in the same directory.
The icons in TextMaker, PlanMaker or Presentations to start another SoftMaker application need a registry entry in the host system. But there is usually no necessary entry in the registry if you start the application directly from a USB stick. That's one of the advantages of the USB installation: You don't need to edit the registry of the host system.
