Installing this patch is highly recommended for all RAD Studio 12.3, Delphi 12.3, and C++Builder 12.3 customers.
Note: The patch includes an updated version of PAServer. This is copied to the patch download folder (Documents\Embarcadero\Studio\23.0\CatalogRepository\12.3Patch-AprilPatch\PAServer), and you need to copy it over to your target devices (Mac, Linux, Windows) and install it manually there.
In addition, for debugging packages in the 64-bit IDE, you should set the LLDB_DCP_SEARCH_PATH environment variable to refer to the lib\win64\debug folder, with a command like: set LLDB_DCP_SEARCH_PATH=C:\Program Files (x86)\Embarcadero\Studio\23.0\lib\win64\debug
And then run bin64\bds.exe from the same command line.
