Hello,

I had a Plustek Scanner with Twain, it worked until the scanner broke.

Now I have an Epson DS-50000 with Twain, but my scanprogramm does not show it in the ComboBox.

My source in the combobox is the following:


procedure TForm1.ComboBox1Change(Sender: TObject);
begin
  ImageEnView1.IO.AcquireParams.SetSource(ieaTwain, ComboBox1.Items[ComboBox1.ItemIndex]);
  FillBack;
end;


What must I do?

Sincerely Peter

Hi Peter

Can you reproduce with our demos?

What version of ImageEn are you using?

Can you generate a log file:

Hello,
With Twain demo 64Bits it does not work. But with Twain demo 32 Bits everything is fine.

Hi Peter

Most scanner manufacturers do not ship 64bit drivers. Do you have any other 64bit apps that can access this scanner?

You should use WIA instead of Twain. For 64bit support on Windows, manufacturers usually include a "WIA over Twain" driver.
