I got error saying Default.Personality is not supported and at least PAServer/ seems not to be patched.
I had uninstalled 22.0 before installing 23.0 (RADStudio_12_3_esd_2017_D8E02C5.exe), registered serial number, got 12.3AprilPatch-20250425.zip, ran patch.R123.hotfix.april_install.bat, but bds.exe GUI did not say the update was installed so I ran Tools, GetIt Package Manager, RAD Studio 12.3 April Patch 1.0. Then the Delphi GUI repeatedly displayed the following error after pressing the OK button: Error | Personality 'Default.Personality' is not supported. [OK] I held down the space bar to push OK many times, then Enter key and the window repeated dozens maybe a hundred times. I clicked the window X a few times and it repeated. I held down Alt+F4 and after a short while Delphi closed (crashed?). I looked in C:\Program Files (x86)\Embarcadero\Studio\23.0\PAServer and the original file is still there (02/27/2025 12:57 AM 289,311,096 setup_paserver.exe) rather than the new ones. Documents\Embarcadero\Studio\23.0\CatalogRepository\12.3Patch-AprilPatch\PAServer\ does exist and contain the 2025/04/25 files. After restarting Delphi the bottom two GetIt tabs no longer say "Error loading data" but populate appropriately and Help, About indicates that the April patch was applied.
