extract java msi from exe

extracting an msi (microsoft installer) file from an exe (executable) file can be useful when you have an installer that bundles its contents in an exe format. many software vendors package their installation files as exe files, which can include msi files, setup routines, or other resources.

prerequisites

to extract an msi from an exe, you will need:
- a windows environment (as exe files are primarily a windows format).
- administrative privileges (if required by the installer).
- tools like `msiexec` or third-party utilities like `7-zip`.

method 1: using command line

some exe installers allow you to extract the msi directly using command line options. here’s how you can do it:

1. **open command prompt:**
- press `win + r`, type `cmd`, and press enter.

2. **run the exe with extraction options:**
- many installers support the `/extract` or `/a` option. the exact command can vary based on the installer. for example:


or


this command might prompt you to specify a destination folder where the files, including the msi, will be extracted.

method 2: using 7-zip

if the command line extraction does not work, you can use a utility like 7-zip, which can handle a variety of archive types, including some exe files.

1. **download and install 7-zip:**

2. **extract the msi:**
- right-click on the exe file.
- select `7-zip` from the context menu.
- choose `extract here` or `extract to "folder_name"`.
- after extraction, check the folder for the msi file.

method 3: using `msiexec` (for msi-based installers)

if the exe file is a wrapper for an msi file, you can often install the software silently and extract the msi using the windows installer service.

1. **run the installer with logging:**
- open command prompt and run:



2. **check the log file ...
