My .exe application that is using an ActiveX control is crashing

[Terry_S]

I am using an ActiveX control that edits video files.  I am building an application that combines all the short clips that I take into a single video file.  The application works fine (both in labview and as an .exe) on my development computer.  However when I install the application on an another computer I get a crash screen, see attached.

I should also say that I created this application in the past using an older version of the ActiveX control and I have no problems.  The reason for the upgrade is to be able to handle color videos.

I have used the ActiveX developers installation package (which is all I did on my devopment computer), so I think all the require files and registrations are occurring.

I have not upload my code, because I cannot figure out how to attach all the required files. So I am hoping someone can look at the errors I am getting and maybe give me some insight as to what I should be looking for.

Thanks

The only clue there is that it's an Access Violation and it happens in "MSVCR71".

"MSVCR71" is the "Microsoft Visual C Runtime" library version 7.1.  You could see if you can update/repair that...

"Access violation" just means some piece of software is trying to access memory it's not allows to access.  Usually this is just a null pointer, which happens somewhere in the binary code of either LabVIEW or a 3rd party addon, such as your ActiveX video stuff.  Not a lot you can do about that unless you can find something in LabVIEW that passes a null reference into the ActiveX nodes.

You response helped guide me through the process and I was able to find an ActiveX method prior to the failure point was causing the problem
