Intermittent Runtime error - pure virtual function call

I have an intermittent runtime error - pure virtual function call & don't know what cause it? Since It only occurs & crashes once awhile therefore it's difficult to trap it for debugging.I suspect it come from TestStand ActiveX API which I use in my User Interface Application project but I'm not really sure.
Does anyone experience this kind of problem when working with TestStand API ? If so any
suggestion? I have noticed in the TestStand API header file teapi.tlh contain many raw_.... function defined as pure virtual function. What are these raw_... function ? I don't think I use any of these function in my project.
Many thanks!

Danh,
I don't believe that your problem can be solved with the information you have provided unless someone else has experienced the same symtpoms which coincidentally have the same cause as in your case.
Is there any other information you can provide that can help localize the problem?
1) What is happening when the error occurs?
2) Does the error always occur in the same place?
3) Does it always occur with use of certain resources (e.g. DAQ, GPIB, VISA, printer)?
4) Does it occur when using the sequence editor?
5) Does it occur when using one of the shipping operator interfaces?
6) Does it occur only when using your operator interfaces?
7)Is it related to a specific sequence or any sequence?
8) Does it happen when you executed your sequence with/without a process model entr
y point (i.e. Execute>>Test UUTs, Execute>>Singal Pass or Execute>>Run MainSequence)?
9) How often does it happen?
10) What version of TestStand are you using?
11) With what language (include versions) are you programming your code modules?
12) With what language (include versions) are you programming your operator interface?
13) Is there any error code reported with this error message?
14) Is this error reported in a TS run-time error dialog or is it reported directly 1by the operating system?
15) Have you searched the web for related errors? For example, the following link describes a particular programming mistake that can lead to this error
http://support.microsoft.com/support/kb/articles/Q125/7/49.asp
By investigating answers to the above questions you may be able to narrow the cause of this error, which might allow you or others to help solve the problem.

After Installing after effects I get a Runtime Error Pure Virtual Function Call

I installed After Effects, the trial, onto my pc which meets all the requirments, and I keep getting a runtime error. I have reinstalled windows, i have used several registry programs and still nothign. Please help!

onto my pc which meets all the requirments
Well, if you are so sure, then why don't you tell us in more detail what PC it actually is? If you have re-installed the operating system and all and AE still doesn't run, then most likely your PC does not meet the requirements or at least uses some strange hardware/ software combination that is not compatible with AE... What operating system? Processor? Graphics card? Other components?

Error "pure virtual function call"

Hi,
Windows7, PCI-GPIB, NI-488.2 Version 3.1.1, Visual Studio 2010 C++ Application.
Randomly between 10 minuntes and 4 hours I get the error "pure virtual function call"
With the debbuger attached to the process in error I identified NI4882.dll as the source of the error.
Then I deinstalled NI-488.2 Version 3.1.1 and installed NI488.2 July 2000. Then my application runs without any error!
I tried to attach the source files which represents the interface between my application and the NI-4882 driver but it did not work for the C++ file.
Any help appreciated.
Best Regards
Walter

Error: runtime r6025 pure virtual function call

My computer crashes when I try to preview my project. It even crashes when I try to preview the classroon in a book project. I have looked on the Internet and have talked to Adobe support several times. Adobe Support has not been able to make any suggestions that apply to my computer...and they hung up on me (twice) after leaving me on hold for a very long time. They keep referring me to Kb 402307 but I don't have DLA service on my computer. The technician said he was checking on something...but eventually just hung up.

I'm sorry for your experience with our technical support people. That is awful. I will be forwarding your message to provide a more colorful data point about what is actually happening.
You haven't provided much information to go on in this posting so I can't begin to guess at a solution.
Looking in our bug database, I see a few mentions of this error around using Multiprocessing (Render Multiple Frames Simultaneously in the preferences) in CS3/AE8 on XP (and only XP) and another issue importing MPEG files. Could either of those apply?
Also, if you let me know what OS and version of AE you are using it would be helpful.

HT203175 I have no problem signing on to iTunes my issue is once on the site I can not use the "search". It says there is a runtime error R6025 pure virtual function call. Has anyone had this problem and how do I fix it. Thanks

I do not have a problem getting in the iTunes stores. My issue is once on the site I can not use the "search". It says there is a pure virtual function call R6025. How can I solve this problem? Do I have to create a new account? Do I have to uninstall and re-install? Thanks

Thanks so much for your feedback. I really appreciate any input here.
If someone from Adobe could GUARANTEE that this problem would go away if I
purchased CS4, I would pony up the cash and do it. However, I'm skeptical
about that because I just saw someone else post a message on the forum today
who is running CS4 and getting the exact same runtime error as me.
I'll try un-installing and re-installing as Admin, and if that doesn't work,
maybe I can find a used copy of CS3.
In the meantime, I'm also wondering if a Photoshop file can carry any sort
of corrupt metadata inside it once it has errored out? Reason I ask is, I
had to port all of my old PSD files to the new computer, and I only seem to
be getting this error when I attempt to work on one of the files that
previously got the runtime error when they were sitting on my XP machine.
When I create new files from scratch on this new computer, they seem to be
working just fine (at least, for now).
If so, I would probably be smart to never open those troublesome
"errored-out" files again.

URGENT: Bug in Adobe Acrobat X /// Acrobat.exe Runtime Error! R6025 - pure virtual function call

Hello
I work usually with large PDF documents, and I was trying to convert a PDF document of 1000 pages ONE THOUSAND PAGES, to little PDF documents of 10 MB each one.
When I tried to convert the PDF file into little ones, craaashhhhhhhhhhhhhhhhhh
I got this message:
Acrobat.exe Runtime Error! R6025 - pure virtual function call - Microsoft Visual C++ Runtime Library
This seems to be a BUG AS BIG A GRAND PIANO... so I would like someone from Adobe tell me how may I solve this problem or if they will release an update soon?
Thank you

Runtime error R6025 - pure virtual function call

I'm running the latest version 10.6.3.25 of iTunes on Windows Vista. When I tried to search in app store using the search pane on the righthand top, it crushes and a box appears saying "Runtime error! R6025 - pure virtual function call".
I cannot search in the app store at all.
Any help?

This bug still exists in Firefox. I tested version 28 and version 32.0.1, which is the latest mainstream release at the time of writing.
Steps to reproduce:
1. It's much easier to reproduce this bug if you are using a computer that has 2 monitors.
2. Load up any Youtube video.
3. Skip advert if required.
4. Click "Full Screen" button in lower right hand corner. The video fills up the whole of the 1st monitor.
5. Click on the desktop on the 2nd monitor - this reveals the taskbar and start menu overlayed above the video.
6. Close Firefox; For example, by right-clicking the "Firefox" taskbar button on the taskbar, and choosing "Close" from the context menu.
7. Firefox closes, but adobe flash player does not close gracefully, and instead throws up "R6025 - pure virtual function call" error message.

Runtime error R6025 Pure virtual function call....the program shuts down as soon as its opened

iTunes shuts down as soon as it is opened. Message says Runtime error R6025. pure virtual function call. What is this and can it be fixed???

If you've already tried a complete uninstall and reinstall try opening iTunes in safe mode (hold down CTRL+SHIFT) as you start iTunes, then going to Edit > Preferences > Store and turing off Show iTunes in the Cloud purchases. You may find iTunes will now start normally.

Captivate 8 - Runtime Error R6025 - Pure Virtual Function Call

My teammates and I have Captivate 8 installed recently and while working on a big project for a client, some of our files got corrupted. We couldn't open them and we'd get a Runtime Error R6025 - Pure Virtual Function Call. Some members of the team could still open those CP8 files but eventually, everyone got the error and we couldn't open the files anymore, even if they were backed up several times.
Anyone have the same problem? We are suddenly having regrets purchasing all those Captivate 8 licenses. Captivate 6 never gave us this problem and it really had to happen with a big project for a client.

Just responded to this in another thread (note we used Captivate 7 so it might be a different error).
We found that when we created files with embedded swf files that existed ABOVE widgets in the timeline, when someone else tried to open our file it broke/we got the runtime error. The original person could still open it for a time, but eventually the cache would clear and they couldn't.
However, if we ensured swf files are BELOW widgets in the source files, it didn't break. In fact, if we found one that was breaking and got the author to move the swf file on the timeline, it would start working for others.
STRANGE! Let me know if this works for you to!

Adobe illustrator runtime error R6025 pure virtual function call

Buenas tardes amigos,
Estoy trabajando sobre una versión Oficial de adobe Illustrator CS 6 con licencia, he realizado una extensión en Acción Script, luego de haber tenido numerosos problemas con la manipulación de imágenes de manera vectoriales en Illustrator con la tarjeta gráfica nvidia GeForce GT 625, decidí cambiar la tarjeta haber si se mejoraba los fallos obtenidos, y si que se nota diferencia ya se cae menos el programa, mostrando el error de runtime error R6025 pure virtual function call, y la tarjeta que estoy usando ahora es una AMD SAPPHIRE R7 250 1GB GDDR5, según he consultado en algunas páginas la tarjeta Gráfica cumple una función muy importante en esta aplicación, por lo que pido ayuda a quien sepa del tema, que solución podría tener en caso de tener que cambiar la tarjeta gráfica por favor decirme por cual, ya que quiero solucionar este problema lo más pronto,

Esta actualizada la versión de Illustrator CS6?
Mac/PC? Sistema operativo?
Qué dice el resto del informe de error al fallar?
Cúal es el nombre del módulo que falla?
Si desinstalas esa extensión, aparece el fallo?
Es decir está asociado el problema a la instalación de esa extensión?
