Coolpack tutorial 9, help needed!

[RvNoel]

I am trying to use coolpack software (that rseems really interesting free tool) and I am not able to solve the exercise 9 of the tutorial dealing with dimensioning tool.

the first part (before accessing to the dimension tool) seems to work properly, the calculated COP agrees with the given solution.
Once the dimension tool is loaded, default values are loaded, so I (again) load inputs, i had previously stored.
Is it OK to do so?(a warning message is displayed in a popup window)

In the SGHX window, when I want to choose "thermal efficiency" option, an error message occurs.

Can someone help me?

Thanks

A few screen captures to illustrate the post:

the dimensioning tool, inputs loaded, fig 2.

The compressor tool, Qe value is not good, fig 3.

The error messages, fig 4 and 5.

Thanks for your help

It looks like there is a bug in the system, suggest you report it to the manufacturers/software builders.

Thank for your advice Brian_UK. I wonder if coolpack is still maintained...
