How to create an MSI installer package quickly and easily

It is not possible to open the MSI file? You are not the only one. Thousands of users are faced with similar problems daily. Below you will find tips on opening MSI files, as well as a list of programs supporting MSI files.

MSI file is supported in operating systems 1. Depending on your operating system, you may need other software for processing MSI files. Below is a summary of the number of programs that support and open the MSI file on each system platform.

Operating Systems

What is MSI file?

MSI extension file refers to the type of files other files. The creator of this file is Microsoft. In addition, the category of other files contains # other files 6033. Windows Installer Package is most often found in operating systems 1. The file will work on Windows systems, but, unfortunately, not on others. The main program supporting this format. Windows Installer. This was created by the user of Microsoft Corporation. As an alternative, you can use # number # other programs. Microsoft Windows, 7-ZIP, Windows Installer XML programs will also process the file when Windows Installer does not play its role.

The most common problem when using Windows Installer Package is that a particular MSI is not related to the program. This is manifested in the fact that MSI files are opened in unusual applications or do not have an appointed program. This problem can be quickly solved by following the instructions below.

The first thing you need to do is just “click twice” on the MSI file icon, which you want to open. If the operating system has an appropriate application for its support, and there is also a connection between the file and the program, the file should be opened.

Install Windows Installer

A problem that is often forgotten about. Make sure Windows Installer is installed on the computer. This can be done by typing Windows Installer in the search engine of the operating system. If we do not have this program, it is worth installing it, as it will help you automatically connect the MSI file with Windows Installer. Below you will find a list of applications supporting MSI files.

View and extract MSI files using an archive

Although the MSI installer file is more like a database, not an archive, some archiving programs can read and extract its contents. Keep in mind that this option will probably be the least reliable. Archives are not as effective as other tools, but they are still very useful to install.

Probably the most popular free utility for archiving, 7-ZIP, can read and extract the contents of many MSI files. Since it behaves the same way as any other readable archive, you can just click the file with the right mouse button and select 7-ZIP open the archive to open the MSI file for viewing.

In an open 7-ZIP window, it is easy to extract the entire MSI or separate files/folders by dragging them from or using the button to extract them. You can also do the same with the teams of the 7-ZIP context menu and extract all the contents of the installer into the folder.

Other free archiving software, such as Bandizip and Peazip, or paid offers, such as Winrar and PowerRart, can also open the MSI installer files. In general, they do not show and do not allow to extract anything different from 7-ZIP, except Winrar. We found that Winrar can open and extract MSI from some files, which other archives could not.

View MSI and extract files using a special tool

A special tool for extracting the contents of the Windows installer files should be the most effective and give the best results. Here we will consider some specialized MSI extractors, all of them are transferred and do not require installation.

A portable and free utility, designed specifically for viewing and extracting files from MSI installation packages, is Lessmsi (also known as Less MsiéraBles). In addition to extracting files, the program also has several additional tabs for viewing data tables from the package and consolidated information stored inside the package (date, languages, numbers of versions, publisher, etc. D.).

Find or drag the MSI installer into the window, and its contents will be shown. All files can be selected for extracting, or you can select several files using a mouse and keyboards Shift/Ctrl. We found that Lessmsi is very effective when reading and extracting more complex MSI files, where other parameters sometimes cannot read all the contents. A parameter for adding/removing the elements of the context menu caused by the right button in the conductor to extract and research is located in the “Edit” menu “Settings”.

The Lessmsi version for the command line is also included in the ZIP archive, so you can remove the installer from the command line or script. The syntax is very simple.

A few more arguments are available, but they are not related to the extraction of the MSI file.

MSI unpacker from JSware

JSware creates several useful tools associated with MSI to facilitate their viewing and unpacking. In addition to the MSI Unpacker tool to be transferred here, they also have a HTA web page, as well as VBScript, which is used as one of the options in Universal Extractor. Just start the program and insert MSI into the window or press the button to find the file.

When clicking “get information about the installer”, the lower panel is filled with all the names and versions of the files inside the MSI, “unpack the installer file” removes all the files to the default folder or into the folder selected by the user. Since MSI packages can add or edit the system register, the “Show registry settings” button will display a list of all registry recordings that the real installation may affect. The list of registry entries or files can be copied to the exchange buffer from the context menu of the right mouse button or menu “Editing”.

Download jsware msi unpacker

The MSITOLS program is used to maintain a magazine in real time, install the command line arguments for MSI files and to extract files from MSI installers. Although the user integration looks quite loaded and complex, you do not need to pay attention to it, because only a few mouse clicks are required to extract files.

Drag the file in the file entry field in the “package” section “or find the file manually. Then just click the “Enjoy the Files” button on the right, find the folder for the output and click OK to extract all the files. If you want to selectively extract files, click the “Files” tab after opening the MSI file. From there you can select/cancel the choice of all files at once or select individual files using the flags provided.

Universal Extractor is a tool that we have already mentioned many times, because it is great for unpacking files of different types. He can also unpack the installers, including NSIS, Installshield, Inno Setup and Windows (MSI) installer. Universal Extractor 2 is an open source code and a more relevant fork of the original version, which has not been updated for several years.

Unpack the MSI file using the right click the menu item or drag the file into the main window. If it cannot automatically extract the file, there will be a hint with three extract methods; Extracting MSIX (Microsoft command line), extracting MSI TC Packer (Total Commander plugin) and expanding the JSware unpacker (MSI Unpacker script for one click from JSware).

If the selected method is not displayed for work, just start the Universal Extractor again and select an alternative method. Please note that Universal Extractor extracts only all files in the MSI package and does not allow you to first look at what inside it.

Possible problems with files in MSI format

Other problems may also be that the ability to work with the Microsoft Windows Installer Installation Package file may also block us. Below is a list of possible problems.

Many files contain data in the form of text or numbers. It is possible that during the opening of unknown files (for example.

It has long been no secret that Windows OS is the most common system among PC users. This is not surprising, since such a phenomenon is easily justified by the functional capabilities that are laid down in it. It is more convenient for the user in different meanings of this meaning. Functionally, it is most developed, has a pleasant and simple integration, and also thanks to it the information revolution has occurred faster. Windows will constantly improve, releasing new versions of the OS, which satisfy all user requirements.

The system uses a large number of different files and data that have different permits. One of them is the format.MSI. This is the format of the Windows installation package. It has information about this OS, as well as information on how to install it. Basically, all the necessary information for the user system. But, this package may contain not only certain information, but also some DLL libraries, which play an auxiliary role, as well as some user scenarios.

This package will be especially useful for users who do not specialize in Windows installation. However, this is not all the possibilities that the installation package has. It can serve in order to update the current version of the system. This is necessary, since each new version is complemented by various functions. There are two ways how to open a format.MSI:

-You can open a file using some utilities, for example, Universal Extractor or 7-ZIP.

If the installation of the file was completed successfully, then in most cases to open it, you just need to press the icon twice. If difficulties appear and the file does not open, then, most likely, there were problems in the register. To do this, you need to go to the register and look for the mistakes that happened to it.

Freearc 0.666

If you compare this with common archives, then 7-ZIP has only three, and Rar uses only seven algorithms. The archiver simply adapts for installation on different systems.

Fails to open a file?

Given the number of file formats and most of them use a file extension with a length of only three letters, it would be reasonable that many of them will use the same letters. This can become quite confusing when they are written almost the same.

Nevertheless, it is important to understand that two equally written file extensions do not necessarily mean that file formats are similar or they can be opened using the same software. You may have a file that looks terribly a lot, the extension says “msi”, but this is really not.

For example, MIS files are either Marble Blast Gold Mission or files with a saved game used by some video games, and they are absolutely not related to Windows installer.

Another is the extension of the MSL file relating to the linguistic files of the comparison specification and the Magick Scripting language files. The former type of file works with Visual Studio, and the latter with Imagemagick, but not one of them works like MSI files.

In the lower line: If your MSI file does not open, make sure that you really are dealing with the MSI file by twice checking the file extension.

Extension files.MSI is ordinary installation packages (distributions) from which the program is set. Unlike the usual “setup.exe “, to start the MSI file, the system uses the Windows Installer service (MSIEXEC process.exe). Speaking in simple words, the Windows installer unzipes and launches the distribution files. When Windows Installer does not work, various errors appear.

In general, it terribly infuriates me, After a stupid error message, it is not clear what to do next. Microsoft specially developed the Windows Installer installer to expand the features of installing programs (this is mainly appropriate for system administrators), but did not take care of the grave operation of this service or at least adequate messages about the problems. And now we will rake it

Charges can be with the work of the service itself or can arise in the process of installing programs when everything is configured, in principle, correctly. In the first case, you need to pick the installer’s service, and in the second, solve the problem with a specific file. Consider both options, but first the second.
