Hi,

Hard to know what’s happening. Did you try to reset your Studio to see if you still the get an error?

Thanks

how can I RESET my Studio?? do you mean to restart the Studio?? I restart the studio and the problem continues, i restar my computer and the problem continues

Sorry I mean a fresh install of your Studio.

I wonder if the problem is easily reproducible or is it something that happens after something “breaks” in the Studio.

Thanks

I reinstalled it ,the problem for execute the designer continues. After that I did another instalation in other path or directory, all works OK, but I had to export all my process(diagrams, pages, data definitions etc) and and import them to the new installation.It was the solution because the previous instalation does not execute the designer.
