Qt5Test.dll error After Deployment of OpenCV application

[MK97w]

Hi Everyone,

I made an OpenCV application for Windows in QT5.15 minGW 32. For deployment i used windeployqt and inno setup for making it's installer.

However, when the application installed to different computers rather than mine, i always observe Qt5Test.dll error.

I have used windeployqt + inno setup for multiple applications and never seen such error before. So i suspect it can be related with OpenCV

Had anyone face a similar issue before?

@MK97w The executable(s) you are deploying would appear to contain unit tests that use QtTest. Bundling the unit tests is unusual not least because they would normally only be built in debug mode..

I forgot to mention that I built the application in release mode and used the output executable for windeployqt.

Also, i didn't add anything to the project QTest related.

If you would not use anything from QTest library then windows would not ask for it. Maybe look with Dependency Walker to see where it comes from.
