Hi Everyone,

I have been creating a toolbox (tbx) using ArcGIS's modelbuilder. I saved it in a .tbx, but the strange thing is that when I open the model from some other PCs it cant be run, and appears like this

meanwhile if I open it from some other PCs it works just fine! The PCs are running the same version of ArcGIS with the same service pack and also the same OS. Its quite confusing this issue.. has anyone faced this errror before? mind to share the reason and solution with me?

Thank you!
