It appears that the .Net Twain dll is compiled for Any Cpu and our .Net control library is compiled for Any Cpu but when we use the SourceCount on the DynamicDotNetTwain object we are getting 0. If we compile our source application for X86 I get the expected result (1) back. Does the version of the underlying scanner driver cause this?

var objScanner = new DynamicDotNetTwain {LicenseKeys = "{Valid key here}"};

var test = objScanner.OpenSourceManager();
Console.WriteLine("Opened {0}", test);
if (test)
Console.WriteLine("Count {0}", objScanner.SourceCount);
for (var i = 0; i <= objScanner.SourceCount; i++)

Spoke with support using Chat and they recommended using 5.4.1 to get the fix for 32 bit / 64 bit in 5.3.

5.3 (07/22/2014)
New Features and Improvements:
Added ScanInNewProcess property for acquiring images in an independent 32-bit process. With the new process, you can now access 32-bit TWAIN scanners from 64-bit applications.
Other minor fixes and tweaks.
