How to allow multiple .msi packages to be installed at the same time?

Question

Windows

I wrote an installer in Advanced Installer. In doing so, it launches another .exe installer, which in turn launches the installation of Microsoft Visual C++ Redistributable. As a result, everything crashes with an error: "Please wait while another application is being installed."
The scheme is: My installer in AdvancedInstaller --> another .exe installer --> .msi microsoft visual c++ installer.
What is the best thing to do in this situation? How to allow multiple .msi packages to be installed at the same time?

Answer 1

Exactly the same as it is implemented in dozens of installers - run sequentially and wait for the installation process to finish.
