Old application won't work under Vista.

Most functions of the old application work in Vista, but it fails if I ask it to acquire an image from the scanner. I am asked to select my twain source, which I do (Samsung SCX4100), but then the scanner gives a couple of grunts and a message box from Vista says "Twain.dll Client's 32-Bit Thunking Server has stopped working". I close the box, am told to check for Windows updates, and finally (when I try clicking around on the application) that "NTVDM.EXE is not responding" and I have to close the application. I have no alternative twain sources to try, just this scanner source. The scanner works fine with other (modern) applications. My c:\windows\twunk_32.exe is version 1.7.1.0 dated 2006/11/02. I believe that it came with Vista. I don't really know what is going on, but I assume that the application is calling twunk_32.exe to handle the actual scanning. It looks to me as if Vista has ways of running old applications like mine, involving twunk_32.exe and NTVDM.EXE, but they are not working on my machine. I would be grateful for any suggestions to fix this. Can your OCR program work with files instead of dealing directly with the scanner? If so, use you newer scanning programs that work and scan the documents to TIFF files. The use your OCR program to do it's thing on the TIFF files. I have done this several times over the years to do OCR when for whatever reason I was not able to do the scan directly from the OCR program. Most OCR programs will not only read the TIFF files but if you put them in a directory together (for multi page documents) it will open the next sequentially numbers TIFF file and do successive pages that way. |

Thanks for replying. Yes, it can do that, and that is what I am having to do at present. |
