LabVIEW crashes 0xAC17A51A in transact.cpp

[Dirs]

Hi everyone,

I have following issue:

A project, with VI, that sets DC output voltage in DAQ card. When I run the file within the project, it returns error, "cannot create DAQ channel" 

There is no possibility to select any channel on any devie device. When I open diagram panel, and create a channel constant, LV crashes with "Error 0xAC17A51A in transact.cpp".

In MAX device working properly, also it does, when I create a fresh file with DAQ functions, or run this VI in standalone mode.

What could be a reason for that? 

Thanks,

Dirs.

How about actually attaching your VI instead of merely talking about it?

Hi nyc,

thanks for ur reply, here is the vi. However as I mentioned, it works in standalone mode. So I was thinking that problem is somewhere in project options, cache etc.

Dirs,

Could you give steps on exactly how you can cause this crash from start to finish?  If there is some simple way that someone else can recreate this issue it will be easier to figure out what is going wrong.

Which DAQ Device are you using?

Thank you guys for responces,

Well, the device is NI PCI MIO 16XE-10 with BNC 2110 board.

Concerning the steps to reproduce, Up to now it is following:

1. PC reboot

2. LV start

3. Open working project (contains >100 VI and device drivers)

4. Run main

5. Open the function that executes above mentioned VI

6. Get an error, that creating new channel task is impossible

7. Stop main

8. Open the VI and trying to select the channel from dropbox, no any channel/device listed

9. Create a new constant/control or selecting in menu "Names filtering" leads to LV crash

10. Device reset, calibration, creating a new project with this single vi or execution of VI separately doesn.t reproduce the crash.

If u need any further info, let me know.

Can you try a minimized example like the one in the attach?

Just change your device

Hey, 

I couldn^t open ur file, my version is 12.0, but i could send a damp file and a log, the problem is still there

And also, what does error -229771 mean? " Internal Software Error occurred in MIG software. Please contact National Instruments Support."

Alright, further googling told me that it could be due to corrupted MAX database - resetting it didnt bring any results.
