Hi uhonermann,
Thanks for the post and sample - Can you advise on the specific version and build of the DLL you're using?
Cheers,

Version of OcrTools.x64.dll ist 7.0.0326.0001
Seems the file is too big, even as ZIP (19,9 MB).

Hi uhonermann,
Thanks for that - You're using an older release, so please download and test the latest OCR module, and advise on whether or not the crash still occurs:

Tried with Version 328, no crash any more.
Will try again with the real application now.
