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?

Do an uninstall and then reinstall. Three's not much else you can do other than that, and if that doesn't work, contact EMBT support directly for help. – Westland

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.

Deleting the .dproj file and opening the .dpr or .dpk, which recreates the .dproj, fixed it for me. HTH

Delphi 11 here. Unfortunately opening DPR just opened it in the IDE like a text file (albeit with code highlight. It didn't recognized it as a project file not recreated the DPROJ. – Refuse

Answer 4

Got the same error previously when running RAD Studio 10.02. Uninstalling that and installing RAD Studio 10.04 did the trick for me.

Answer 5

I got the same Error, but for me I combined most answers, and it works well on Delphi 11.2 so here is my steps:

1. Just open and close (as admin) several times.
2. Open the .dpk only!
3. Close it then open the project again and it works just fine.

Answer 6

I've got this error after installing Visual Studio.

For me it fixed itself when i open Delphi as admin, close, and open again.

Answer 7

I wondered if it relates to Visual Studio usage at same time as Delphi .. and debugging in both .. Closing Visual Studio and Delphi and reopening Delphi corrected message/issue for me.
