[TRNSYS-users] TRNSYS Wizard Problem

Dear all,

 I made the simulation using TRNSYS Wizard, however, after that I got a
TRNSYS Bug. Please see the attached figure which is the bug I met. (English
meaning:*.bui file contains an invalid path )

Do you experts have some solutions or advices for that?

Once I use the TRNSYS Wizard to produce other any new program, it appears
this bug all the time. If I can not deal with it, I will not continue to
work using TRNSYS.



Many thanks in advance!

Br.

wang
