Dear:
I'm making a model of a catalytic cracking plant, when I specify a flow in a stream (687) and I run the program, a screen that stops working Hysys specifying:
Problem event name: APPCRASH.
Application Name: hysys.exe
Application Version: 23.0.0.7119
Fault Module Brand: 493ecc57

I have not found the solution to the problem, and I try with 2 computers with windows 7 32bit and throws me the same error in both.
Please if anyone can help me solve this.
In advance thank you very much.
