where did you get this .dll and who is it signed by?
Hi David,
I just googled it. But cant tell now from where I downloaded it because i visited so many places searching for a solution...
Do you have a specific download ? Please ?
Windows normally comes with twain_32.dll.. I think your problem is calling unmanaged code from managed code
David
Can you please explain what is "calling unmanaged code from managed code"
and what canI do to recover my twain_32.dll I may have overwriten my original....
thank you
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.
