[Windows] Zero Install lets you download and use programs without having to install them [Mac OS X, Linux]

Zero InstallIt’s already typical for a Windows user to download and install a software or program. It is also the responsibility of the user to keep its program up-to-date. This could be a hassle especially to those who do not regularly update their programs. Luckily, there’s a simpler method that you can use to run and update your Windows apps. With Zero Install, you don’t even need to install your programs on your PC or laptop.

What Is It and What Does It Do

Main Functionality

By now, you might be wondering what this Zero Install system is all about. Well, it is basically a decentralized cross-platform software installation system that allows you to run and update your programs. Compared to the usual software installation process, this system is rather different because there’s no need for you to install your software or apps. Just search its catalog, choose the app that you like, run it and that’s it. You’re all set to use the program.

In other words, Zero Install lets you download/update, run, and use programs without having to install them. Essentially, you run all programs supported by Zero Install as if they were portable.

Take note Zero Install supports Windows, Mac OS X, and Linux. We specifically reviewed the Windows version.


  • Neat and user-friendly UI, responsive and very stable
  • There’s no need for you to install any software or app – you can just run the app directly via the Zero Install system
  • Zero Install has a catalog of supported software. If the catalog doesn’t have a program you want to use, you can run your own custom software provided that you follow the system’s official packaging guide.
  • You can integrate your programs so that you can easily access them through your start menu or desktop
  • Automatic software updates – your programs will be automatically updated every time its developer gets to publish a new version to its website
  • Supports auto-sync – will automatically integrate and transfer your application list from one computer to another
  • You can use programs’ previously released versions – e.g. If you prefer the version 5.9.8 of Notepadd++, just click its drop-down menu then choose “select version” instead of the latest version
  • Zero Install allows you to run programs without admin access, programs that would normally require admin access
  • Zero Install itself has portable version
  • Zero Install claims “software developers publish programs directly from their own websites” and that “digital signatures are always checked”, which means there shouldn’t be a big risk of accidentally download malware disguised as a legitimate program. However, always have your antivirus up-to-date in case something goes wrong.
  • Is open source


  • Its catalog, while extensive, does not contain *all* of the programs that you might want to install on your computer so if ever you want to run a program that is not available on its list, you are required to follow the steps indicated in its packaging guide which is, of course, are not that easy to do especially if you’re just a normal (non-techie) user
  • There’s no advanced search option – you cannot search for apps by developer, category or tags
  • There doesn’t appear to be an online version of Zero Install’s supported software catalog — the catalog is only available via Zero Install itself, meaning you have to download it before you can learn if a certain program is supported or not
  • It isn’t clear if Zero Install required. NET Framework or not, and if .NET Framework is required then what version


Zero Install CatalogThe Zero Install system is a splendid concept that possesses a great potential. Keep in mind that if you use this system, you can run and update your Windows applications but it won’t install anything on your computer. Everything goes through the Zero Install platform. This has been made possible because of the system’s unique method of allowing the software developers to publish their programs directly from their own websites.

What’s great about this system is that it already has a large collection of Windows applications. All you need to do is to choose the app that you like, run it and then you’re free to do whatever you want. For first time users, you will be guided by the system’s video tutorial. After that, you can start searching its catalog to see if there’s a program that would best suit your needs or demands. For example, if you want a reliable video or audio editor, there’s Audacity and Avidemux. Once you’ve found the program that you like, click the green “plus” button that is located next to the software’s title and then you go to “My Applications”. In this tab, find the software that you’ve recently added then click “Run”. This will prompt the system to download the necessary components needed to run the software and once everything is set, it will automatically load the software or program.

Do take note that the downloading process could take some time but this is only a part of the initial set-up. So the next time that you open the program, it will no longer go through the same process. For easy access, you can also opt to place your program into your start menu or desktop. You can do this by clicking the “Integrate” button that is located right below the “Run” button.

Another notable feature of the Zero Install system is its ability to load a program’s previous versions. You can easily set this up by clicking the drop-down menu that corresponds to your chosen program. Of course, you can easily revert back to the latest version.

While Zero Install apparently flaunts a very interesting and reliable method of running and managing a wide variety of Windows applications, it is still need not capable of providing all of the Windows apps that you want. Furthermore, the process for adding custom apps is something that can only be done by advanced users.

Conclusion and Download Link

Zero Install is an interesting program, to say the least. Aside from the fact that Zero Install lets you run programs without installing them, a favorite feature of mine is how Zero Install lets you run older versions of software in case you ever upgrade to a newer version only to find it to be buggy.

Overall, I feel Zero Install is definitely worth a try. Just keep in mind, if Zero Install’s catalog does not have a program you want to use, you will have to follow some extra steps to make it Zero Install compatible. Check it out.

    Interesting find. Tell me, what are its advantages over Sandboxie for example. Sandboxie doesn’t required you to install duplicate framework (ie. .NET) to run its programs.

    Also Sandboxie permits multiple sand boxes, so an install that doesn’t behave well, doesn’t wreck other apps running in Sandboxie.

    [@hipockets] The necessary components vary per program but as I’ve said, it won’t install anything on your computer. As for user-created files (ex. new .avi, .wav, .jpeg, .doc files, etc.), you can save those files to your computer.

    The GAOTD issue is the “GOTD Themida” I have no issues in a company wanting to protect it’s clients however rogue software like this one can install whatever junk on your computer and you woudn’t know… but for peace of mind I use Total Uninstall : http://www.321download.com/LastFreeware/page11.html this way any crap that’s been changed to my pc i’ll know about it as for making portables out of GOTD apps most tools such as Sandboxie will not work as the installations are now hooks only time Sandboxie will work is with a activate as it’s only a registry key that gets run.

    But speaking of today’s program Zero Install what I love is you can actually see the source code which gives more trust in using it.

    [@hipockets] I haven’t used Zero Install myself, so I’m hoping Kent can clarify this. My guess, however, after reading about Zero Install is that sometimes necessary libraries are needed to run a program (e.g. .NET Framework) and such libraries are downloaded if you don’t have them installed.

  • hipockets

    You wrote “This will prompt the system to download the necessary components needed to run the software…..”

    Does “necessary components” refer to the complete program? Or does it refer to the code put on the user’s computer that will put Zero Install in touch with the appropriate program on Zero Install’s server?

    How are user’s files (such as a new .txt file) handled? Are they stored on the user’s computer? If so, can the user specify the storage location?

    If P-Apps in the list (32bit) works as advertised, then I have the solution to GAOTD re-installs later. I hate that they, and others like them, cannot be reinstalled later on a new PC or Laptop like FREEWARE can. The other ones were 64bit.

    I don’t mind the extra effort to download and jump through the stupid hoops to get a final download and install it – if I know It can be re-installed later.

    I like Portable better too.

    Thanks for pointing me in the right way.

    Ashraf once told us all years ago that it is a conflict for him to tell us how. Understood, I guess.

  • drvajra

    I tried a similar program called “Cameo”. It is pain – when installing a new program it takes an awful lot of time, and after installation yet more time. WHAT’S MORE, the AVG reported virus in the proggy. Hope this one is not similar.

    [@davidroper] It’s like a Linux repository. They provide the software, not you. Both are open-source, and supposed to be convenient, secure, and reliable.

    What you’re looking for is application virtualization, which you can find here: http://www.techsupportalert.com/content/probably-best-free-security-list-world.htm?page=0,9

    Never tried a GAOTD program, but they should work in theory. Sandboxie sandboxes and virtual machines are movable as well.

    [@Ashraf] It’s like Nancy Pelosi said about the Affordable Care Act, “You have to pass it to find out what’s in it.”

  • davidroper

    Am I misunderstanding this (like I always do) ?

    Can I use this to “install” a GAOTD program, and make it “Moveable” so I can save it for use later? Notice I did not say “portable”, just move it to a CD or DVD for use later?

    And thank you always for not laughing a Soda out of your nose around me. ;-)

  • Ashraf

    [@GF] I couldn’t find the list of supported programs on their website either — I guess you must download it to find the list.

  • Ashraf

    [@Quick Brown Fox] Wrong. Zero Install itself comes in a portable version which you can download, if you don’t want to install Zero Install.

  • GF

    I don’t find the list of the available programs.

  • Quick Brown Fox

    This informative article fails to mention one important fact about this product’s misleading name: In order to use Zero Install you must first INSTALL it!

  • GF

    This program would be useless if many damned programmers created software that don’t put down roots into our dear PC.
    I wonder if such programmers will ever stop to do that.

  • Donna Rae

    I think this is a great concept! Like a cloud for backup files but not a cloud. Pretty soon we won’t have to keep any info on our PC’s or disk. Fine by me!
