More information here.

@Blackzero if using qmake:

CONFIG += force_debug_info

If using cmake:

CMAKE_BUILD_TYPE=RelWithDebInfo

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.

without having to redo the code

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

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

Maybe its time to switch to cmake after all

include(InstallRequiredSystemLibraries)
will install VCRuntime* dependencies in the install step.

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.

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).

You should deploy release builds of your app not debug. If you really want to deploy debug builds then also provide debug versions of these libraries.
