Hi,

i used FR 2026.1.6 with Rad Studio 12.2 Win64, everything worked fine.

After migration to Rad Studio 13.1 Win64x, first try with FR 2026.1.7 printing is working but runtime formular design brings Access Violation #0

Nothing had to be changed for migrating with FR use, no compile warning/hints.

Then i tried:

2026.1 is running

2026.1.1 is running

2026.1.2 and all above till current 2026.1.7 has the same issue with AV when trying runtime designer.


Are there any known problems with Win64x in that versions?

Regards,

Sascha

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.
