Windows normally comes with twain_32.dll.. I think your problem is calling unmanaged code from managed code

twain_32.dll should be in the C:\Windows folder.

Check for it there.  Under Properties for that file should be the following:

File version 1.7.1.3
Product version 1.7.1.0

Also do that for the other versions in your computer and report back what you find.

After performing a sfc -scannow I found :

c:\windows\twain_32.dll                      file version 1.7.1.3 product version 1.7.1.0
c:\windows\system32\twain_32.dll                        1.7.1.1                              1.7.1.0
c:\windows\syswow64\twain_32.dll                       1.7.1.1                              1.7.1.3

Get rid of the one in c:\windows\system32

If the one in c:\windows\syswow64 was one you copied there then get rid of it as well.
