    Default Uninstall Chrome before doing an update?

    ON my old XP based machine it appeared that whenever I updated Chrome it would install the update and the entire browser onto my drive while keeping the previous version as well. Could have been my imagination I suppose. I got into the habit of uninstalling Chrome and then downloading the new version. I'm now running Win 7 Ultimate 64 bit with Chrome as my main browser. Is it recommended that I uninstall this version first before getting the latest update?
    Thanks! Any suggestions would be appreciated.

    My understanding is that the whole point of Google Updater is that the user doesn't have to bother. Updating any Google product will happen in the background seamlessly and incrementally.

    I'm using the portable version of Chrome from portableapps.com and so I have to download the new stable version when available. This installed over the old version without problem when I went from 0.0.375.55 to .99.

    Chrome keeps the previous version of the install when it updates (in the Applications folder) this is a feature ...

    Mind you it would help (I suppose) if they gave us a 'roll back' feature to utilise it !!

    Hi Steve,

    If you have time could you please read and then comment on the two links I'm giving?
    http://blog.chromium.org/2009/07/sma...safer-too.html

    And then here's a link to a page on a forum whose mod seems a bit tech-savvy though what he says (and the link above) have me totally confused as to the significance / mechanism of how Chrome is updated for those who go with the Google Updater route:
    http://broadbandforum.in/software-di...18/#post397876 (and a few subsequent posts).

    BTW, a new stable is out:

    I believe "Chrome keeps the previous version of the install when it updates" is more just a fact of the situation than a feature. That's just how the Courgette incremental updater works.
    http://www.chromium.org/developers/d...ates-courgette

    For details, see also:

    http://code.google.com/p/chromium/is...il?id=10548#c3
    "Yes [seeing two folder versions] is expected if Chrome was in use during update. This old version should go away in the next update."

    http://code.google.com/p/chromium/is...l?id=10548#c11
    "The in-use update that Chrome supports while maintaining the same location for chrome.exe is fairly convoluted. Sometimes you might even notice new_chrome.exe living besides chrome.exe. But like I said subsequent updates do clean it up."

    But also:
    http://code.google.com/p/chromium/is...l?id=10548#c20
    "We are looking in to fixing this ( see http://crbug.com/22293 ) so that old versions get deleted, but to be clear it is absolutely not a security vulnerability. We are looking into fixing it because it's not polite (and there's no great reason) to leave the old cruft around and take up extra space on the harddrive."

    And to reply to bigbobbysd's question, no it is not necessary at all to uninstall old Chrome versions before installing latest updates.

    And as vasa1 says, "the whole point of Google Updater is that the user doesn't have to bother. Updating any Google product will happen in the background seamlessly and incrementally." Yes, this applies to Chrome and all other Google software you have installed (eg. Google Earth, Picasa, Picasa Screensaver, etc.)

    I'm running Win 7 Ultimate 64 bit. Where and how do I find the application folder so I can delete previous versions of Chrome. As you say, I don't see the value in having them saved since there's no roll back feature. Certainly wish there was..........
    Thanks for any further help you can provide, Thanks and peace!
