Hi
It might be worth renaming the 'Lib' Folder in your project folder to say lib_old.
Then in tools re-scan sources, then clean and rebuild your project.
The Lib folder should be re-created a new for your current environment and cpu bitness.
Worth a shot.

Thanks, I've tried, the lib directory has been recreated, but I become the same error.
I have copied all my files of the project into a new directory and compiled, now it works.
Maybe there were something in the directory of the project that comes from 32 bit, but nothing with the EditBtn, so I cannot understand the error message.
Best regards,
Stephanie
