frxDbDataset - Edit Field Aliases command causes Access Violation error

Using: FastReports 6 VCL Professional, Delphi 10.2.3 Tokyo

I have a TfrxDbDataset on a data module, and its linked to a dataset. When I right-click on the frxDBDataset component and select 'Edit Field Aliases', there is causes Access Violation error.

This is happening both with release version (ver 6.8) and the latest update (ver 6.8.6).

The exact error message is:

 Access violation at address 1BE69FE9 in module 'frx25.bpl'. Read of address 00000140.

I have MadExcept installed and the first few lines of the stack trace is as follows:

thread $3438:

Could this be a bug? Or is something wrong with my installation (outdated files etc)? Can you help resolve it? Its urgent. TIA.


  • I've now resolved the error. It turns out there were older BPL files all over the system (in Windows\System32 and the regular RAD Studio BPL folder location). After deleting these files and re-installing FastReports, it now works perfectly.

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
