Need a little guidance

[TheBoss]

Somebody in my company developed a Vensim model for me, and now, years later, I want to update the inputs and see what the outputs are. However, I am unfamiliar with the software. Would there be anybody who would be so kind as to help me navigate the basics - where to overwrite the old data inputs with the new ones, and how to get the output in the same tables as before? Hoping this would be a small task, but I could compensate as appropriate.

I'd start with the tutorial at
http://www.public.asu.edu/~kirkwood/sysdyn/SDRes.htm

It will take you through the basics of how to use Vensim. That might be enough to get you going.

Thank you. I had not seen that before. I think I'm making some headway. Is there anybody who might want to serve as a paid consultant on this, in case I need to accelerate?

I have downloaded Vensim PLE x64 and Vensim Model Reader x64, but neither will open four old .vdf files. PLE says the file type is not known, and the Reader hangs and never opens or closes the file - I have to restart the computer to get it to clear. How can I open these with full model functionality?

VDF are results files, you typically load them into a model rather than load them as a model.

The best option would be to use the licence that was purchased to develop the model, that will probably be old enough to run the model as developed.
