Deployment of an application with .dll

Podaz98

Dear all,
I create a .dll with LabVIEW and I import it in my Qt project and verify that works.
Now I'm trying to deploy my app by "Qt 5.15.0 (MinGW 7.3.0 64-bit)" but an error appear .

How I can deploy these applications?

Many thanks to all.

@Podaz98 What does the error message say?
Did you deploy the DLL together with your app?
Was the DLL build using MinGW or MSVC compiler?

@jsulm The message say "code execution cannot proceed because ChangeVal.dll was not found...."
How can I deploy .dll together with the app?
DLL was generated by LabVIEW. I'm using MinGW.

The final app binary SimpleGUI.exe and the ChangeVal.dll should be in the same folder. Try to keep them both in the same folder and let us know.

@foxoman I already done it. At that point I see the following pop-up "Application Error 0xc000007b".
