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-22.214.171.124-hotspot\ 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.
