how to solve the error when the application is opened on another laptop

So I have to build the release in qt creator

Yes.
Debug build expects *_D or *d debug libraries and release the release libs (e.g. without debug symbols).

Hi,

One detail that comes from the top of my head, the debug version of the MSVC runtime are not redistributable.
One alternative is to do a release with debug information build.

[Blackzero]

@SGaist What does that mean? How to do that?

If you are using CMake adding
include(InstallRequiredSystemLibraries)
will install VCRuntime* dependencies in the install step.

@Mesrine seriously !? oO

Maybe its time to switch to cmake after all

[Blackzero]

@Mesrine I use qmake, how is the code if in qmake

[Blackzero]

@J-Hilk
I have too much code that makes it impossible to move to cmake, is it possible to change qmake to cmake easily without having to redo the code

You don't have to change code when you change the build system.

[J.Hilk]

@Blackzero the correct way to ship those particular dependencies that seem to be missing, is actually by having the user install those runtimes themselves:
https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-170

or by shipping the installer yourself (you're explicitly allowed to do that) and executing it during your app install process.

@J-Hilk except that the error message talks about the debug version of the runtime which is not redistributable. More information here.

@Blackzero if using qmake:

CONFIG += force_debug_info

If using cmake:

CMAKE_BUILD_TYPE=RelWithDebInfo
