After installing yesterday's new version opening Delphi 12.3 results in an access violation loading Sparke,,Sphinx & RemoteDB design-time packages. There was no error reported by the install which was done using the Smaty Setup GUI version 1.7.
Sorry to say this, but I can't reproduce it. I tried in a clean VM with 12.3 and installed all TMS BIZ in all platforms.
Just to be sure, this is my version of 12.3:
Embarcadero® RAD Studio 12 Version 29.0.55362.2017
What is the exact error message you receive when opening Delphi?
Have you tried open the menu Components | Install Packages and try to disable/re-enable the packages to see what happens?
Or maybe remove the offending packages and then trying to run a tms build to reinstall again?
Finally, maybe check for leftovers of previous installations to see if somehow the IDE is trying to load other BPLs (previous versions) or something like that?
