Delphi 12.3 won't start anymore - exception in RTL290.bpl

[MatthiasPeters 1]

Hi,

I have Delphi 10.2.3 running stable for many years now. Recently I installed Delphi 12.3 and with that version I had trouble from the start: very often when I quit the software I couldn't start it again. A solution was to rename the last used .dproj file. Then Delphi 12.3 starts and I can rename the .dproj file again and load it manually.

Since yesterday, even this doesn't work any more. I get the following error message:

---------------------------
Anwendungsfehler
---------------------------
Exception EAccessViolation in Modul rtl290.bpl bei FFFFF064.

Zugriffsverletzung bei Adresse 00000064 in Modul 'bds.exe' (Offset 64). Ausführung von Adresse 00000064.

---------------------------
OK   
---------------------------

The IDE then resides in the background and cannot be used. Is there any way to see a log-file or something to check where the program start fails?

I don't know about log files from IDE.

Have you installed the latest May patch (you can find it on Getit)? You can also download it on MyDownloads of Embarcadero.

 

Uncheck the options "Tools/IDE/Saving and recovering/

"Reopen last open project ..."

 

so the IDE start without loading a project.

 

 

P.S.: If you have any third-party add-ons installed, try uninstalling them all and adding them one at a time to see which ones might be causing you problems.

Thank you, that was indeed a helpful advice, after I got the IDE starting again, I switched off that "Reopen last opened project" option.

And here is how I got the IDE starting again:

I took some config file and gave it the ".dproj" extension. Then I doubleclicked it to be opened with RAD Studio 12.3. That gave a nasty error message but at least the IDE stayed open and I could do the change of the "Reopen last opened project". Now it seems that everything is working fine again!
