have problem loading .vmf file

[vensimer]

Hi everyone,
I'm new vensim learner here. I found an interesting vensim-based simulation from the internet. it's made by other people. i need to install this vensim application first to run this simulator. i wanna to check how this model was built, so i went to the installation root directory and found what i wanna see. But when i try to open this model (.vmf file) using Vensim PLE or vensim model reader , it failed to open it. I check the error history , the error is corrupted block reading file. But i dont know why. Cause i know vensim can read the .vmf file. Can any one here tell me what's going on and how to solve this problem or open the model correctly?
I would really appreciate it. Thank you!

If you want to get access to the model you will need to contact the people who created the application and request a copy of the model from them. The vmf files that ship with a redistributable application can only be opened by that application.
