I have 64 bit Windows and 64 bit Python . I want to install twain in my machine . So I have download this link . I did what readme file said . Copied twaindsm.dll into system32 and SysWow64 file. Then I have used twain like I said in this question . Then I test if the driver is installed .So for this purpose I download twacker. In the twacker when I execute the 32 bit : enter image description here

I can see my scanner devices and connect to it . When I execute the 64 bit : enter image description here

There are no scanner device to connect and this result is the same like this post . So the problem is 64 bit twain does not installed correct ? If so how can I install because I download twain 64 . Pls anyone help me ?

Cause of the Problem

The main reason is that most scanner vendors only support 32bit TWAIN driver.
