ImageEnView1.IO.TwainParams.VisibleDialog := True;
ImageEnView1.IO.AcquireOpen;
It cannot work normally on the win64 platform, unable to scan and cannot close the twain form

Hi
Not all drivers support the AcquireOpen() method. Can you test your project using the FreeImage Software scanner driver:
https://sourceforge.net/projects/twain-samples/files/TWAIN%202%20Sample%20Data%20Source/
It works correctly with 64bit when we test it here.

HI!
I have compiled the demo into 64 bits, and set ImageEnView1.IO.Acquire.VisibleDialog := True; and call AcquireOpen.
call Acquire--->OK(twain form can work normal)
call AcquireOpen----->Error(twain form can not work normal) |

Hi
To display the Twain form, you should enable: ImageEnView1.IO.Acquire.VisibleDialog.
Do you have any 64bit applications that are able to acquire on that system?

Maybe you don't understand me.
it means Calling AcquireOpen on the win64 platform cannot operate the Twain form, but calling Acquire can |

After calling Acquire, the twain form will automatically close, AcquireOpen don't.
I need to keep the twain form open,Until I turn it off manually |

It looks like you are using an old version. Also that demo line should be: ImageEnView1.IO.Acquire();

you can use "Demos\imageendemo\ImageAcquisition\Twain\TwainDemo.exe"
compile it into a 64 bit program, and then try the effect

Hi
AcquireOpen() uses Twain. Acquire() can use Twain, WIA, etc.
Can you explain more about what you are seeing and the error that you get?

the version is 10.0.2
ImageEnView1.IO.Acquire; //this can work normally on the win64 platform,but AcquireOpen |

Hi
What version of ImageEn are you using?
Unfortunately most scanner manufacturers do not include 64bit drivers at all, so you should check whether there are any available for that device.
You should use WIA instead of Twain. For 64bit support on Windows, manufacturers usually include a "WIA over Twain" driver.
