I downloaded the OCR with Layout Demo and when I run
the OCRwithLayout.exe and
with the Engine of Cube or Accurate I get
Access Violation at address 10396642 in module ievision.dll
read of address 00000000
running this on win7 64bit
Running 'Fast' engine it works.

Actually both OCR demos seem to AV error constanty. More complex image it flips out. It seems to work when its a pure black
and white image. But any water marks or anything in the image, and no go city.

I get an access violation using the C++ OCR demo when I use other than one of your demo OCR images. I get the access violation, for example, when I load the test.png file from your Barcode demos.
I have attached a screenshot of the access violation error message.
I am using XE5 Update 2 on Windows 7 64 bit (but creating a 32 bit program). I am using versions of ImageEn and IEVision that I just downloaded. I did have to make two modifications of your sample code in order to get it to compile and link. There were some old references to version 16 of some of the libraries in the .cbproj file, so I simply deleted those, and I had to change
IEVisionLib->createOCR("eng", ievOCRFAST, false, OCR);
to
IEVisionLib()->createOCR("eng", ievOCRFAST, false, OCR);
Otherwise, the demo app is not modified at all.
Again, no access violation when loading the sample images you provide with the OCR demo, only when loading other images.
Thanks!

That post does not say where the TESSDATA registry entries are, but I don't see any in HKCU/Software/Xequte . Is there anywhere else I should be looking?

Because the post you referred me to says that the solution was deleting a key from the registry, but did not say exactly where that key was found. That key was my best guess as to where I should be looking.
In any case, the "Find" function of RegEdit did not find "TESSDATA" anywhere in the registry on this computer, so I don't think that is the problem.
