So I have download <a href="http://sourceforge.net/projects/twain-dsm/" rel="nofollow noreferrer">this link</a> . I did what readme file said . Copied twaindsm.dll into system32 and SysWow64 file. Then I have used twain like I said in <a href="https://stackoverflow.com/questions/34855258/using-twain-module-in-python?noredirect=1#comment57450358_34855258">this question</a> . Then I test if the driver is installed .So for this purpose I download <a href="http://kb.dynamsoft.com/questions/644/How+to+use+TWACKER+to+check+if+my+device+is+TWAIN+Compliant%3F" rel="nofollow noreferrer">twacker</a>. In the <a href="http://kb.dynamsoft.com/questions/644/How+to+use+TWACKER+to+check+if+my+device+is+TWAIN+Compliant%3F" rel="nofollow noreferrer">twacker</a> when I execute the 32 bit :

  <p>There are no scanner device to connect and this result is the same like this <a href="https://stackoverflow.com/questions/34855258/using-twain-module-in-python?noredirect=1#comment57450358_34855258">post</a> . So the problem is 64 bit twain does not installed correct ? If so how can I install because I download <a href="http://sourceforge.net/projects/twain-dsm/" rel="nofollow noreferrer">twain 64</a> . Pls anyone help me ?</p>
