Working exe stopped working....need advice to debug

[Anuj]

Hi,

I have a VI that runs a TestStand seq file dynamically using the TestStand OI controls. I built an exe out of this VI two months back and have had it working since then.

As lame as this might sound, since yesterday, the exe does not work anymore. As soon as I double click on it, it invokes two instances of the LabVIEW run-time engine immediately in the task manager and right after that, it goes into Not Responding mode. If I run the VI by itself (out of which the exe was built), the VI works fine. I also noted that if I run the VI by itself, it does not invoke any instances of the run-time engine.

So I am really confused as to what could have changed without me making any change to the PC or the system/setup anywhere that is not making the exe work anymore. I built an exe out a simple VI and that worked. So its not like the Build Executable utility is not working properly.

I am really confused. Any suggestions that will help me debug the problem will be really appreciated.

Thanks

Was something modified in the folder?  Deleted file?

Was the vi modified?  where it waits for a user prompt but the vi or sub vi is not displayed? or is there a loop that prompts for user input, but no delay in the loop and the popup window does not appear?

I had a similar case related to a vi that was waiting for user input but didn't appear. I had to use show vi when called.

Your description is very close to what I am experiencing.

The TestStand seq file that gets dynamically run from the VI does have a file prompt to begin with. All these VIs exist in a library and some VIs (that had nothing to do with this particular VI) did get updated just recently.

Let me try your suggestions and see if it works..
