There is the requirement for XML document to have exactly one root element.
The error informs that ".dproj file" which is the document in XML format does not adhere to this requirement and thus malformed.
Perhaps, the .dproj file has been corrupted.
Two components: UniDBGrid (class TuniDBGrid) and UniDBVerticalGrid (class TuniDBVerticalGrid) showed erratic behavior in Embarcadero Delphi 11 environment. Both of them gave out error “Argument out of range” after placing om form. The mouse became trapped inside the form and it was difficult to release.
Several other components from some Categories: uniGUI Standard: UniCheckBox, UniGridPivotExcelExporter, UniStringGrid, UniFieldSet, UniFieldContainer, uniGUI Additional: UniBitBtn, UniDBEdit, uniGUI Data Controls: UniDBNumberEdit, UniDBMemo, UniDBHTMLMemo, UniDBNavigator, UniDBListBox, UniDBImage were tested and looks like they worked as expected.
Either UniDBGrid or UniDBVerticalGrid did not generate any errors and were workable in Embarcadero Delphi 10.4.1 environment.
An interesting fact: if the project is created, these components are placed on the form and everything is saved in the Delphi 10.4.1 environment, then these components and the project is workable if opened in Delphi 11.3.

Simple corrections brought in THexEditor, THexToCanvas by Valient Newman to make the component meet the requirements of Delphi 6 and higher, when the design-time and runtime code must be separated.
Changes published September 6, 2023
Updated 15 dec 2025
Corrections were made to comply with Delphi 2009 requirements.
Checked in Delphi 7 and Delphi 2007, 2009
This component is used in Activity and Authentication Analyzer
The component HexEditor is available in My Github Repository
THexEditor descends from TCustomGrid, and displays and edits hexadecimal/binary files THexToCanvas is a descendant of TComponent, assign a THexEditor to it, set some properties and you can paint the hex data to a canvas (e.g. printer canvas)
