How can I install Windows software or games?
Short answer
.exe files are not binary-compatible with Ubuntu. There are, however, compatibility layers for Linux, such as Wine, that are capable of running .exe.
Detailed answer and solutions
The underlying problem:
Ubuntu is a completely different system than MS Windows. Not only it looks differently, but it also uses different mechanisms for its core functions.
The problem with .exe files is that they are specific to Windows. No other system is capable of running them, because their contents are designed to work on a Microsoft's system. Linux uses different standards, different concepts, and therefore Ubuntu applications need to be adapted to them to work correctly.
If you have just migrated from Windows and are doing your baby steps with Ubuntu, you may be indeed surprised that .exe files fail to run. There may be different symptoms, either an error message may appear, or there may be no effect at all when double-clicking an .exe. This all happens, because Ubuntu has no idea what should it do to run that file. Ubuntu is not knowledgeable about how MS Windows works "behind the curtain", and therefore it can't execute the code that's within them. In technical jargon, one says that Windows and Linux executables are not binary-compatible.
Looking for alternatives
The first thing you should do is to realise that most likely you do not want to run that .exe file. Most Windows applications you are used to have their Ubuntu alternatives in Ubuntu Software Center.
Therefore the very first step when you try to run an .exe file is to check whether there is a Ubuntu version of the same application (like Firefox - it has both a Windows and Ubuntu edition), or a close alternative, which is not the same app, but does 99% the same stuff. For example, if you want to compose a document, instead of MS Office you will want to use LibreOffice.
How can I find an alternative?
Here are some tips.
- Search Ubuntu Software Center.
- Launch the Ubuntu Software Center, type in the search box what kind of application you are looking for. For example, typing in "photoshop" finds The GIMP, which is a great advanced image editing tool, and is a great substitute for Adobe Photoshop.
- Many Windows applications are also available for Ubuntu, and have their identical version in Ubuntu Software Center, which is the preferred way of installing software in Ubuntu.
- Search Ask Ubuntu (this very site).
- There are many questions here that explain what applications can be used as substitutes. Also, do not forget to ask a question if you need software-recommendation.
- This Ubuntu Help page contains great tips when seeking for alternatives.

Okay, but not all applications have alternatives. There are a number of cases where you will want to run the .exe program anyway. Examples include:
- You are trying to run an application of which alternative makes no sense. In case of most video games you will want to run them and not an alternative.
- You may want to run the original application instead of an alternative, because the alternative is not good enough. For example, many people consider Photoshop to be a much better editor than The GIMP.
- This is a very Windows-specific program, that makes little sense on Linux.
Luckily, you can get .exe files to run on Ubuntu.
Running .exe files on Ubuntu with WINE
What is Wine? Well, technically it's a compatibility layer. What it means is that it provides an environment similar to Windows to any .exe application you try to run. Therefore, with WINE .exe files will run on Ubuntu.
WINE is not installed by default. You can get it either by:
- Searching for "wine" in Ubuntu Software Center.
- Running the command:
sudo apt-get install wine.
Details on installing WINE can be found in this question.
Okay, so I installed WINE. Now what?
Proceed to launching your .exe file! Double-click it, and with a bit of luck everything will seem like on Windows. Voilà!
WARNING: Not all applications will behave correctly when run with WINE. WINE is by no means perfect, and because it pretends to be a Windows environment instead of actually being a real one, some applications may malfunction. Common problems may include incorrectly displayed fields, fullscreen issues with video games, copy-protection problems. Some of them can be solved with litte hassle, make sure to check the WINE application database and use google to find hints in case your .exe does not work correctly.
Running Windows applications on Ubuntu with PlayOnLinux
There is another tool you may like which aids you in running Windows applications.
It's called PlayOnLinux (website) and it supports quite a wide range of software (browse).
What it does is it runs a specific version of Wine which is known to work best with the application you are willing to run. It also installs additional paths to provide maximum compatibility with Ubuntu. But you don't need to know about that; everything is done automatically.
Because of that, PlayOnLinux tends to provide the best results in case of running a widely known piece of software, including many video games.
Installing PlayOnLinux:
- Find it in Ubuntu Software Center, or
- Run
sudo apt-get install playonlinux
Using PlayOnLinux:
Instead of double-clicking the .exe (which launches it with WINE), run PlayOnLinux application. Select "Install" button on the toolbar, and choose what application you wish to install. PlayOnLinux will guide you through the installation process (of course you will need installation media).
Once it's done, your installed application will be displayed in PlayOnLinux main window. Double click to launch it!
Commercial solutions
If you are not satisfied with WINE, there are some commercial softwares that runs Windows applications on Linux. One of the most well-known is CrossOver. In some cases it has significantly better results, yet it is not available for free.
You can if you first install the
Wine compatibility layer 
from the Software Center, you can install Windows applications in Ubuntu. Be warned though that not all applications work perfectly or without glitches. Some applications are even unusable, while others work perfectly (see the Wine Application Database for a good idea of how well various programs work). see How to install and configure Wine? to help you to install this.
Once Wine is installed, you can simply double click an .exe or .msi file to run it. If this doesn't work for some reason, right-click the file and select "Open With Wine Windows Program Loader". Of course, only run executables from sources you trust to avoid Windows malware.
If you run into compatibility issues, you may wish to try the latest Wine Beta version from the ppa:ubuntu-wine/ppa software source (see What are PPAs and how do I use them?).
You might also consider installing Winetricks , CrossOver or CrossOver Games to install and use software more easily.
To see the debug output of Windows software (in case something goes wrong) run it from a terminal using wine msiexec /i file.msi or simply wine file.exe.
yes by using wine.
get it by going to the Ubuntu software center.
here is a link to the ppa https://launchpad.net/~ubuntu-wine/+archive/ppa
here is a video on how to install http://www.youtube.com/watch?v=hZgjgeDQVo4
here is a video on installing basic applications http://www.youtube.com/watch?v=RLRLWEfdFqY&feature=related
and here is wine wiki which will provide you with some more information. http://wiki.winehq.org/HowTo
if you wish to play a game from a CD you can install play on linux which is also available in the Ubuntu software center. hope this helps
