Earlier in ICE error checking with
ORCA I mentioned that Wise Package Studio had means to detect ICE
errors and errors in general. To look for errors in Setup Editor
click

The problem is that Wise Package Studio always report this error:

And
this is after we have resolved all the ICE errors that ORCA
complained about.
If you try to fix this you'll break the package.
In Wise's defence, however, the error checking function did help me once to resolve a problem that was preventing me to compile an MSI.
