how to solve the error when the application is opened on another laptop
-
I have a problem with the MSVC2019 compiler after doing windeployqt, the application opens properly on my laptop after deploying, but when other laptops open it errors occur etc. as below, I have used 2 ways to deploy yes it does set VCINSTALLDIR and does not set VCINSTALLDIR, but both as usual it works for my laptop but does not work for other laptops, how to solve this

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.

@jsulm So I have to build the release in qt creator and then redo the deploy with --release?
@Blackzero said in how to solve the error when the application is opened on another laptop:

Yes.
Debug build expects*_Dor*ddebug 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. -

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

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@Blackzero said in how to solve the error when the application is opened on another laptop:

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

@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_infoIf using cmake:
CMAKE_BUILD_TYPE=RelWithDebInfo
