Shockwave Flash Crashes In Google Chrome

Shockwave Flash Crashes In Google Chrome

Many users of the Google Chrome web browser report problems with the Adobe Flash Player plugin – the problem has continued from Chrome 10 through to the current Chrome 21.
When trying to browse a Flash-based website e.g. Facebook games, YouTube or use tools like Google Mail (which also rely on Flash) in Google Chrome, the Flash plugin crashes with a message saying: “The following plugin has crashed: Shockwave Flash“.

What Does That Mean?
Ignore the reference to Shockwave – the error message ‘the following plugin has crashed: Shockwave Flash’ means that the Adobe Flash Player plugin has crashed – it has nothing to do with Adobe Shockwave Player which is a separate program.

What Causes The Crashes?
Recently in updating Adobe Flash, Google Chrome already includes an integrated version of Flash Player which is automatically updated by Chrome – there is normally no need to download the standalone Adobe version of Flash Player which is intended for non-IE users (primarily Firefox).
However, if Firefox or a similar web browser is (or has ever been) installed on your computer, then you have likely also installed the standalone version of Flash for Firefox/other web browsers – and this would include Chrome.
Chrome 21 was released, one relevant change is that it has reintroduced the ‘experimental’ PepperFlash plugin – and made it the default Flash player (at least on the W7 and XP systems I have tested). Early reports from some users report audio and video problems as a result of using Pepperflash.
Chrome may therefore have up to 3 versions of Flash Player installed – the new default PepperFlash plugin, the Chrome version and maybe the standalone Adobe version too. Having two or three versions enabled often causes ‘the following plugin has crashed: Shockwave Flash’ error message because they may conflict with each other.
The aim is therefore to disable all except one Flash plugin.

How To Fix It
  • Open Chrome.
  • Type   about:plugins   into the website address bar at the top and press the ENTER key to display Chrome’s Plugins page.
  • Look down the list of Plugins for ‘Flash’ – if it says ‘Flash (3 files)’ you have Adobe and Chrome versions of Flash installed and PepperFlash. If it says ‘Flash (2 files)’ you have the Chrome version and PepperFlash – both cases may cause Chrome to crash when accessing Flash-based websites…
  • Click on the ‘+ Details’ link at the top right of the Plugins page to expand the list of all Plugins.
  • Scroll down the list to find the Flash plugins – you should now see the full details of the Flash plugins which may display up to three versions of Flash:
chrome4
Flash Plugins including Pepperflash and (optional) Adobe Flash)
  •  Look at the ‘Location:’ of each version – the integrated Chrome and PepperFlash versions are in (…Application Data\Google\Chrome\Application etc) whilst the standalone Adobe (formerly Macromedia) version is in the …Windows\system32\Macromed\Flash etc directory.
If you have 1 version – Chrome:
  • Download and save to your computer the latest Adobe standalone version of Flash (this is the non-IE version).
  • Close Chrome and then install this Adobe Flash you just downloaded. The recent Flash 11.3 version offers the option of automatic silent updates – recommended to keep it up to date automatically in future.
  • Open Chrome and go back to about:plugins – you should now have 2 plugins (Chrome and Adobe).
  • Click on ‘Disable’ just under the Location of the Chrome version to disable it – it will become greyed out. Ensure that the Adobe version is enabled – if it is disabled (greyed out) click the ‘Enable’ link just under its Location to enable it. Now close the Plugins tab.
If you have 2 versions – Chrome and Pepperflash:
  • Click on ‘Disable’ just under the Location of the Pepperflash version to disable it – it will become greyed out.
  • Ensure that the Chrome version is enabled – if it is disabled (greyed out) click the ‘Enable’ link just under its Location to enable it. Now close the Plugins tab.
    If you have 2 versions – Chrome and Adobe (no Pepperflash):
    • Click on ‘Disable’ just under the Location of the Chrome version to disable it – it will become greyed out.
    • Ensure that the Adobe version is enabled – if it is disabled (greyed out) click the ‘Enable’ link just under its Location to enable it. Now close the Plugins tab.
    • Download and save to your computer the latest Adobe standalone version of Flash (this is the non-IE version).
    • Close Chrome and then install the newest standalone version of Flash you just downloaded. The recent Flash 11.3 version offers the option of automatic silent updates – recommended to keep it up to date automatically in future.
    If you have 3 versions – Chrome and Pepperflash and Adobe:
    • Click on ‘Disable’ just under the Location of the Pepperflash version to disable it – it will become greyed out.
    • Click on ‘Disable’ just under the Location of the Chrome version to disable it – it will become greyed out.
    • Ensure that the Adobe version is enabled – if it is disabled (greyed out) click the ‘Enable’ link just under its Location to enable it. Now close the Plugins tab.
    • Download and save to your computer the latest Adobe standalone version of Flash (this is the non-IE version).
    • Close Chrome and then install the newest standalone version of Flash you just downloaded. The recent Flash 11.3 version offers the option of automatic silent updates – recommended to keep it up to date automatically in future.
    Final Steps
    Start Chrome and visit the Adobe Flash Player test page to check that Flash is now properly installed and working ok.

    Tip:
    From version 11.2, Flash offers automatic updating so it can update itself on a regular basis. Update Checker to automatically check for new updates as it can check for updates to many other common free programs e.g. Adobe Reader, QuickTime etc.

    Other Tips:
    The above fix has worked for most but there are many different reasons for Flash crashing in Chrome so, if it doesn’t work for you, here are some further tips that may help:
    1. If you only had 2 versions (Chrome and Pepperflash), download the latest Adobe non-IE standalone version of Flash then close Chrome and install that downloaded Flash program. Then just follow the steps in the ‘If you have 3 versions’ section above – effectively you will be disabling Pepperflash and Chrome Flash and utilizing Adobe Flash instead – hopefully that will resolve the problem. 
    2. Try the ‘How To Fix It’ steps again but the other way round i.e. this time Enable the integrated Pepperflash and Disable the Chrome and Adobe versions – then test to see if Flash no longer crashes. You could also try with just the Chrome version enabled and the other(s) disabled. 
    3. See if Flash works ok in Incognito mode (click the Wrench/spanner in menu bar and choose ‘New Incognito Window’ to start Incognito Mode). Incognito mode disables all Chrome Extensions – if Flash now works without crashing then one of your Extensions must be causing the problem so, once back in normal Chrome mode, disable your extensions one at a time and test Flash until it stops crashing. The last extension disabled is the one causing the problem – leave it disabled and enable the others again. 
    4. Disable all Plugins except Flash. If Flash now works without crashing then one of your Plugins must be causing the problem – enable your Plugins one at a time and test Flash until it starts crashing again. The last Plugin enabled is the one causing the problem – disable it and enable the others again. 
    5. Update yours graphics card drivers (especially if they are old). Driver updates are often released to fix an issue with how Windows or individual programs work with a piece of hardware (e.g. graphics card) or to enable new features for it. 
    6. Disable Flash hardware acceleration to eliminate hardware or driver compatibility problems with Flash Player – untick ‘Enable Hardware Acceleration’ in the Flash Display panel. To view the Display panel, right click the picture (application image) during playback of a Flash video and, from the context menu, select ‘Settings’. The Display panel is the first panel (tab) shown at the bottom of the Settings window. 
    7. Test Flash on another browser such as IE or Firefox – if it crashes there too then skip to step 8. If it does not crash there, your version of Chrome may be corrupt. The last resort is to uninstall Chrome and ensure you clear the browsing data during uninstall.

      Then, reinstall the latest stable version (currently Chrome 21) and the problem will hopefully be fixed. Remember to backup all your bookmarks/passwords etc BEFORE you uninstall – you could also sign into your Google account and sync settings for use later.

      From comments received, the above fixes have worked for the majority of people. If you do still have problems with Chrome, you may have to wait for a specific fix from Google. In the meantime you could use the other browser (e.g. Firefox or IE) if necessary.
