Is it possible to run another installer while installing something in Windows?
Question
I have an.msi installer developed using wix that installs some dlls in a directory on the file system. Some of these dlls have dependency on Visual C++ Redistributable Packages for Visual Studio 2013. I am wondering that is it possible to install that run time (downloaded from https://www.microsoft.com/en-us/download/details.aspx?id=40784 ) during my installer's installation process? - that is while the.msi installer is running and copying dlls, it will install the MSVC run time at the same time for the user.
I want to know if this is possible.. If it is, is this generally a good or bad practice? Should it be enough to just copy the MSVCP120.dll and MSVCR120.dll along with all other dlls? Thanks.

VC++ Runtime : The Visual C++ runtime can be installed via merge modules ( basics ) inside the MSI ( there are some limitations with later versions of the runtime ) or as an executable on its own ( vcredist_x86.exe or vcredist_x64.exe ), generally installed before your main MSI ( latest C++ downloads ).
Setup.exe : You can bundle such a runtime installer inside a setup.exe made with WiX's Burn feature ( Hello Burn example - it is a bootstrapper, chainer, launcher - runs installs in sequence) or a similar feature in InstallShield ( suite projects ), Advanced Installer or other packaging tools . Some resources: More on Burn and Making setup.exe launchers .
Universal CRT : As stated in this answer, it is recommended to use the vcredist_x86.exe or vcredist_x64.exe installers instead of the merge modules due to the "Universal CRT" components not being installed properly with the merge modules. "Universal CRT" relates to Visual C++ support for Universal Apps built for the Universal Windows Platform .
Single File Copy : Please avoid copying single files to the location application folder. This is important in order to be able to rely on system-wide security fixes for the C++ runtime (coming down from Windows Update or installed in other ways).
