Perché 4.57.21?
Perché è una solida soluzione di compromesso, apprezzata dalle flotte miste:

• Una versione di riferimento affidabile quando si confronta il comportamento tra le configurazioni

Attenzione prima di iniziare

• Utilizzare una macchina con spazio su disco sufficiente (i dati di programmazione sono grandi ).
• Esegui come amministratore quando necessario e mantieni semplice il percorso di installazione.

Hi Bin. Unfortunately, after a few seconds of starting Istagui, this window appears indicating a bug. I've reinstalled several times, following your instructions exactly, but every time Istagui stops starting. Why do you think this happens? Obviously, I'm asking for help, not just from you, but from everyone. Thanks.
