lvrt.dll error

[Gary McW]

Hello,

I get an lvrt.dll error in my Labview 2010 program. I have Labview runtime installed as well as DAQMX. The runtime computer is Windows 7 based computer also the program runs fine on the development computer but not the executable also a windows 7 computer. I have read the many links to this issue in the forum but there does not seem to be a clear solution is National Instruments working on this issue.

Thanks

What error message do you get?

Similiar to this. I can get a print screen in a few hours when it happens again. The program will run for like 5 yours before the error.

Ah. You get an application crash.  Bad thing. 

Do you have any idea what the application did before the crash?

This is an access violation.  I have been producing with DLLs I have written in C by reading from or writing to a memory location that is not owned by the application.  I do not think that there the problem is your LabVIEW code.  It might be a bad combination of device drivers on your PC.

Does anyone else have a good idea?

When it crashes on the development computer there is a different error. These are the files it references. Only when running as executable.

WERBCEC.tmp.WERInternalMetadata.xml
WERE592.tmp.appcompat.txt
WERE5F1.tmp.mdmp

Here is the error in XP as well thought I would try. 

ModName: lvrt.dll

ModVer: 10.0.1.4004

These files will not help us.
Your application crashes after about 5 hours. How about memory usage? Did you open Task Manager and verified that the memory usage is almost stable?

[Gary McW]

Ya that was the first thing I checked no memory leakage. 

[GuenterMueller]

Very good.

Does your application reliably crash after operating for about 5 hours?  Is the app doing anything special at that time?
