Twain under x64?

Mikael Fredriksson May 15, 2012 08:29AM EDT

Hello,

I've built a DLL (C#/.NET4) which is using your DTI.ImageMan.Train.DLL (version 3.10). However, when I compile my DLL as X64, I get an error when trying e.g. to enumerate installed scanners.

On the other hand, if I compile my DLL as X86 it can't be loaded from my application (which is X64).

Is this a known problem? Can you suggest a workaround? Error logs are availble, if you need them.

Best Regards,

Mikael

Hello Mikael,

ImageMan.Net Twain offers full 64-bit support. However, when building your apps as 64-bit assemblies, you will not be able to access 32-bit Twain drivers. Since scanner manufacturers have not currently developed true 64-bit drivers at this time, you will most likely need to continue to set the target platform to x86 to access the 32-bit Twain drivers.

Thanks for your interest in our products and please let us know if you have any questions.

Sincerely,
Sean
