For use with Delphi Tokyo, you need to replace the package dependency to upfcoredxe11.dcp
Do you write location of this file to check please. Because it seems that it is not exist in my computer
This is normally in the default output folder of the IDE for compiling packages:
Hello Bruno, this file is not exist and samples are not working, probably setup file for the Delphi 10.2 is incomplete. Please check.
Did you compile the project file upfCoredxe11.dproj ? It should generate upfCoredxe11.dcp under folder C:\Users\Public\Documents\Embarcadero\Studio\19.0\DCP
Sorry, it was my typo that I wrote upfCoredxe11.dcp while it should be pfCorePkgdxe11.dcp that you should find in the install folder if you installed the trial version. It is with the registered version that it will be in the folder C:\Users\Public\Documents\Embarcadero\Studio\19.0\DCP
