During startup FastDetect 2.exe an error occurs.

OpenCV Error: Unspecified error (The node does not represent a user object (unknown type?)) in cvRead

Error in function cvLoad

In version 2.4.13, developers began to switch to the new Haar cascade file format. This was due to the development of the OpenCV 3.0 branch. The developers broke cvLoad for Haar cascade and recommended using C++ classes (CascadeClassifier cascade). Some Haar cascades remain in the old format, such as haarcascade_frontalface_default.xml. Other Haar cascades need to be tested. Also look in https://github.com/opencv/opencv/tree/master/data/haarcascades

the examples don't work with any cascade (at least it didn't work for me) Doesn't work at all anymore?

None of .xml files work. All xml files both in facedetectxml and in facedetectxml_new folders seem to be bad/broken.

I always get this error: OpenCV Error: Unspecified error (The node does not represent a user object (unknown type?)) in cvRead, file C:\build ... \core\src\persistence.cpp, line 5008. EExternalException: External exception E06D7363

Try to test Delphi-OpenCV\samples\MultiDemo\FaceDetect\FaceDetect.dpr It normally loads "resource\facedetectxml\haarcascade_frontalface_alt.xml"

I've tried that project. It fails with all .xml files as well. OpenCV is compliled with VS2015, Delphi version is 10.2 Tokyo.
