Runtime Formulardesigner fails under Rad Studio 13.1 Win64x with 2026.1.2+

sloewen_fullsystem · March 25

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

Update:

If i run with UsePackages=true, it's working.

if i run wuth UsePackages=false, it's not working.

i tried mini-projekt, same error is coming up (since 2026.1.2, also current 2026.1.8)

Debug exception:

Class EResNotFound with the message 'ControlsButtons resource not found'. Process FastReport.exe (8128)
