Since a very long time, my application which is using Dvtk library v3.1.0.2, is returning an error on other computers. Something like: FileNotFound exception on DvtkManagedCodeAdaptor.dll or one of its dependencies.

This error generally occurs on Windows XP or Windows Server 2003 systems. But sometimes it is the same even on Windows 7 systems too.

I found this topic on the forum:
http://www.dvtk.org/modules/newbb/viewtopic.php?post_id=1215
But the "use a reference path without blanks" stuff didn't solve my problem.

Finally i tried to replace my library files with previous version v3.0.6.0. And it worked just fine.

I could continue with this previous version, but my main problem with previous version is; there are no such properties "CallingAETitle" and "CalledAETitle" in the DvtkHighLevelInterface.Dicom.Messages.AssociateRq class. I really need these properties.

The weird thing is library returns no error on my PC. Only when i try to run application on other computers the error occurs. And not all of them, %70 returns this error, %30 works fine. But i could not resolve the main reason.

So, what are the real dependencies of latest DvtkManagedCodeAdaptor.dll? What is the difference between them?

I digged a bit with "Dependency Walker".
There are two dependent DLL giving warning:
"IESHIMS.DLL" and "WER.DLL"

But i think these are not very important files, since they are also giving warnings for the previous version of "DvtkManagedCodeAdaptor.dll".

LS,

I just uploaded the latest windows 64 bits compatible version of our library. You can download it through http://www.dvtk.org/modules/wiwimod/i ... +Library&cmenu=developer.

Can you try again if this solves your problems?

Make sure you are using the release dll's of DVTk and build a release executable of your application, otherwise it will not run on a non-Visual Studio pc.

Hi marco.

I've tried what you said, used the release build of Dvtk and release build of my application. But it is still the same even with those latest 3.1.4 version.

The strange thing is; if i copy the "DvtkManagedCodeAdaptor.dll" from old version 3.0.6 directory and use it with new 3.1.4 DLL's, my application starts working again.

What exactly that dll for?? Is it some kind of C#<->C++ wrapper?? And would that be ok if i use old 3.0.6 version "DvtkManagedCodeAdaptor.dll" with new 3.1.4 version other Dvtk DLL's ??

There is another topic here about this subject:

And i see you say you currently don't know what causes this error. But i'll be glad if you consider this problem as a critical work item and i hope you'll find the main reason soon.
