I got this error in log after installing this version.  
It would be nice when the script .train is compatible for Delphi 11.3 too.

Hi,

update `c_EW.train` as

```auto
ide64_versions = temp_ide64.split(';'); //changed

```

and relaunch `install_HY.cmd` with admin rights. it will solve this issue.

note: files are located in `C:\Program Files (x86)\RemObjects Software\Build`

I think I should update the file `r_EW.train` as well in the line 25, like this:

`ide64_versions = temp_ide64.split(';');`  
and relaunch `register_HY.cmd`.

or am I wrong?

Because I have an error in Registry too:

The KnownPackages for bds37 win32 are wrong, should it be BDS37 instead of BDS31?  
And the bds37 win64 are not registered

Hi,

changes for `r_EW.train`:

```auto
ide64_versions = temp_ide64.split(';');

```

&

```auto
function _getBDSHive(_version)
{
	if (_version == 7) return "Borland\\Delphi\\7.0";
	if ((_version >= 9) && (_version <= 11))	return "Borland\\BDS\\"+(_version - 6).toString()+".0";
	if (_version == 12) return "CodeGear\\BDS\\6.0";
	if (_version == 14) return "CodeGear\\BDS\\7.0";
	if ((_version >= 15) && (_version <= 19))	return "Embarcadero\\BDS\\"+(_version - 7).toString()+".0";
	if (_version >= 37) return "Embarcadero\\BDS\\"+_version.toString()+".0";	
	if (_version >= 20) return "Embarcadero\\BDS\\"+(_version - 6).toString()+".0";
	error("unknown Delphi version: "+_version);
}

```
