Dynamsoft TWAIN Products

I'm evaluating dynamic .net twain, but I've been unable to get the demo projects to scan. Calling the SelectSource function displays the dialog window (and lists the scanner correctly) but on calling OpenSource displays the following error:

---------------------------
This application has failed to start because DRIOP.dll was not found. Re-installing the application may fix this problem.
---------------------------

Any suggestions?

Thanks,
Laura

Hi Laura,

Have you tried acquiring images from your scanner from the scanners and cameras wizard that comes with Windows? If so, how is it going?

If the scanners and cameras wizard can successfully get images from your scanner, please reinstall Dynamic .NET TWAIN and try the sample application again.

Also, you can take a look at the following page showing the possible cause of the problem and how to solve it.
