Thanks for the response Jim.
Soon after I posted I found some google results that mentioned the same thing about IEShims.dll.
I have the TWAINDSM dlls in the right locations for the tests I am running. My code is successfully being built as x64 and x32.
If I attempt to run the x64 application it will start up, but I don’t have any 64-bit data sources so I can’t test what happens when I try and scan. Do you know of any scanners that have 64-bit twain DSes?
When I run my x32 version of the app it still fails to scan. Even the sample from this site (twain.org) doesn’t run correctly. To clarify, neither works on Vista / Windows 7 64-bit OS.
If I run the sample on Windows XP SP-3 32-bit it scans successfully. I ran out of time last night before I could get my app over to the VM. I will try that tonight.
I have the logging working now (requires a reboot to get the environment variables to take) so I will be going through them to see what the differences are. Based on a quick browse of them last night it looks like the calls to Enable to DS are failing; no condition code or other info is available in the log, just TWRC_FAILURE.
I’ll post again when I have more details.
