There are a lot of times when you don’t actually need admin privileges to install that bundled-up *.msi.

Take AdoptOpenJDK binaries for instance.
You can simply run:

msiexec.exe /i OpenJDK11U-jdk_x64_windows_hotspot_11.0.7_10.msi INSTALLDIR=%USERPROFILE%\AdoptOpenJDK\jdk-\ MSIINSTALLPERUSER=1

The important settings are the: INSTALLDIR= which has to be a directory where you have write privileges and the MSIINSTALLPERUSER= which with the setting of 1 will install it as a single user.

Also tested to work with 7zip.
