Problem on Windows 7 64 bit machines

Post by Abacus » Sun Mar 14, 2010 09:23 PM

Win 7 64 bit machines return "Library not initialized" error on start.
TwainAdvanced.exe in "C:\Program Files (x86)\VintaSoft\VSTwain.NET.6_0\Bin\v2.0\64-bit" folder works properly but when I try TwainAdvanced sample in Visual Studio i get the error.

Did I have to do anything else for 64 bit machine?

Thanks,
D.

Update:
This error is gone if compiled as x86. Now works but I do not see the WIA option that I see on a 32 bit machine.
Also only works if scanner UI is suppressed.

Thanks,
D.

Hello,
This error is gone if compiled as x86. Yes, you should compile your project in x86 mode on 64 bit systems.
Now works but I do not see the WIA option that I see on a 32 bit machine. I think your device does not have WIA driver for 64 bit systems.
Also only works if scanner UI is suppressed. Please send information about your device, snippet of your code and log-file to support@vintasoft.com and we will try to fix the problem.

Best regards, Alexander
