step 2 - error loading packages

[SoyYako]

Friends, we continue with the test.
If we ignore the previous error (described in step 1) and continue until the wizard finishes.

When the wizard finishes, we open IDE and when starting the process of loading the environment, Delphi displays the following error messages (three consecutive messages):

---
