Delphi.Personality is not avaliable

Question

Recently, I get this error, and all Delphi-related project/file creation items are missing:

The project can not be loaded because the required personality Delphi.Personality is not available..

What I need to do is select "Manage Platform" and then RAD Studio will reinstall some components and restore the project menu.

However, the issue will occur again when I close and re-open RAD Studio.

I did not have such a problem before. Does anyone know how to fix it?

Answer 1

I got the same error, closing and opening delphi 11 for several times, the problem fixed. It looks like that's a temporary error.

Answer 2

Got the same error. This worked for me:

In the IDE, open Tools - Manage platforms and hit Apply (without changing anything)

Close/open the IDE a then the project opens fine.
