I'm having the same issue as well. Moved coding on my app from an x86 machine to an x64. Changed all the Leadtools modules to the 64-bit versions and now _twainSession.Startup fails with "No Twain Library". Any ideas guys?

Please don't assume that you are facing the same issue mentioned in the old post.
Please provide more details about the problem you're facing and include the following details:
1- Does Twain scanning work on the same machine using 64-bit Twacker?
You can get 64-bit Twacker using this link:
http://twain.org/docs/Twack_64.msi

2- Which LEADTOOLS version (15, 16, etc.) are you using?
3- What build of LEADTOOLS DLLs are you using? To find the build, right-click on Leadtools.Twain.DLL -> Properties and check the version tab.
4- Does the problem appear if you use one of our demos? If yes, please mention the details on how to reproduce it.

A couple of things...

On my old 32-bit machine I had a test twain driver from the Twain folks that won't run on the 64-bit one (won't even install...). Do you know of a test 64 bit one out there I could use instead of hunting down a scanner (not an easy task @ my office).

I'm using Leadtools v15, file verion on the module is 15.0.1.8.

Thanks for the reply...

There is a 64-bit twain driver (data source) that you can install. Go to www.twain.org and click on the link named "Sample Data Source & Application 2.0".
