How to solve the problem of automatically installing two programs and adding one certificate to the registry?

Question

Automation

Essence of a question - there are two programs and one certificate. It is necessary, if possible, to create a package or an installer that will install both programs in a certain order, and then add a certificate to the system. Without rebooting and additional actions on the part of the user, except for launching the package itself.

Answer 1

Use any program for creating installation packages, either native Microsoft or something third-party like InnoSetup
If your programs already have a convenient installer that can be controlled from the command line, you can get by with one batch file - Run the installers of the necessary programs in "silent" mode, and install the certificate .
You can install a certificate from the command line using the Certmgr.exe utility.
Sometimes, if the programs are not very complicated, a banal winrar or 7z is enough to create a full-fledged installer.
In general, installing any program is

• Unpacking the right files to the right places (easily solved with the help of an archiver)
  
• Registering libraries - this can be done from the command line.
  
• Making entries in the registry if necessary - again, the batch file will help
  
• Create Shortcuts
  
• Performing some additional actions - for example, in your case, importing a certificate.
