OK, on a 64-Bit Windows, the key seen by a 32-Bit application like ModelMaker is HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Embarcadero\BDS\19.0

The code for checking the presence of a Delphi IDE is like this: function IsDelphiIDEInstalled(IDEVersion: TDelphiIDEVersion): Boolean; var R: TRegistry; begin R := TRegistry.Create; try R.RootKey := HKEY_LOCAL_MACHINE; Result := R.OpenKeyReadOnly(DelphiIDEKey(IDEVersion)); finally R.Free; end; end; DelphiIDEKey evaluates to Software\Embarcadero\BDS\%d.0 for the newer versions. Note that ModelMaker is only aware of BDS versions up to 19.0 (Delphi 10.2 Tokyo). You might get away with just creating the base key for a non-installed version to trick ModelMaker into looking for the expert. So adding HKLM\Software\Embarcadero\BDS\19.0 to the registry should get you going.

Is this in HKEY_LOCAL_MACHINE? If yes, there might be other criteria being checked for existence of a Delphi version. I'm willing to investigate, but my possibilities in regard to ModelMaker are a bit limited compared to MMX.

That's possible. IIRC ModelMaker looks for the BDS\xx.x\Experts key in HKLM.

Same here and this is how the dialog looks here:

I couldn't reproduce, but I am on 12.3 here. Can you give detailed steps to reproduce? Perhaps I tested something plain simple while the real problem is more complex.

Well, in this case you can. I did a lot of refactoring such code myself during the last decades. The constraint you suggested to remove is a good indicator of progress in such an endeavor.

There are several bugs fixed in 12.2 and 12.3 affecting frames. https://quality.embarcadero.com/browse/RSP-37402 https://quality.embarcadero.com/browse/RSP-39847 https://quality.embarcadero.com/browse/RSP-40110 https://quality.embarcadero.com/browse/RSP-43560 https://embt.atlassian.net/servicedesk/customer/portal/1/RSS-1020 Perhaps these will fix your problem, too. I will test your project later when I've found some time to configure my system for monitors with different dpi.

I just took what the OP wrote and show a way to revert any file somehow changed from ANSI to UTF-8. I never said it is a silver bullet for all circumstances.

Because it is the reverse of what Notepad in Windows 11 did to the files.

Load the file with UTF-8 encoding and save it with ANSI encoding. uses System.IOUtils; ... TFile.WriteAllText(FileName, TFile.ReadAllText(FileName, TEncoding.UTF8), TEncoding.ANSI); If the files are too large to fit into memory, you need to work with different file names for input and output: var writer := TStreamWriter.Create(NewFileName, False, TEncoding.ANSI); try var reader := TStreamReader.Create(FileName, TEncoding.UTF8); try while not reader.EndOfStream do writer.WriteLine(reader.ReadLine); finally reader.Free; end; finally writer.Free; end;

Isn't the root problem where you read these strings in the wrong way and shouldn't it be handled right there?

Looks to me like some caching problem in the IDE. As you seem to have reproducible steps, you should file a bug report.

You can avoid that by setting MarkDisabledItem to False.

Add an event handler for OnEnableItem and set AEnabled := False;
