FlashPlayerPlugin - Application error message - "The instruction at 0x71a30000 referenced memory at 0x71a30000. The memory could not be written"

Since upgrading to Windows 8 Pro (with a downloaded upgrade, not a "clean" instal, so all my apps and settings were retained) I get the following error message when starting my customised version of Firefox with several pinned tabs, or when flash content loads in an uncustomised version in another user account, or when that version is closed if no flash content is loaded :-

(Title) - FlashPlayerPlugin_11_5_502_110.exe - Application Error

(Content) - "The instruction at 0x71a30000 referenced memory at 0x71a30000. The memory could not be written. Click on OK to terminate the program"

This also happened with the 11.4.402 version prior to today's update.

I have tried running the browser with add-ons disabled, and uninstalled/re-installed Firefox, but the problem remained. Can anyone tell me what the problem is and how to fix it?

I have found the solution to my flash problem (see my reply to cor-el), so I hope it also answers yours.

If you have TrusteerRapport on your computer then open Task Manager (as Administrator), then under processes click on each of the three Rapport entries and click end task for each. Then run Firefox and try it, I hope it solves things for you too. Be aware that, unless you uninstall Trusteer, it will start up again if you do a restart, and you will have to repeat this step. I am about to send a report to Trusteer asking if they are aware of this and have it in hand.

If you don't have Rapport, then perhaps a similar program which runs in the browser without being a plugin or extension may be to blame. Good luck!

I upgraded to Windows 8 pro yesterday and it's noticeable that explorer works fine on all websites... firefox has this same error message and I've spent an hour disabling and enabling add-ons, updating plug-ins and downgrading to last version but it still has the same problem!

Help....

You can check for problems caused by recent Flash updates and try these:

  • disable a possible RealPlayer Browser Record Plugin extension for Firefox and update the RealPlayer if installed
  • disable protected mode in Flash 11.3 and later
  • disable hardware acceleration in the Flash plugin
  • downgrade the Flash player to version 10.3

For me, the problem was with Trusteer. An update of Trusteer is available which solves this issue. All okay now.

Thank you for your response. I had already come across these suggestions but they are not relevant to my problem as they relate to issues that occur once the flash plugin is running, in my case the problem was that the plugin would not run. However you have led me to the actual solution through the link to the flash troubleshooting page which I had not seen before, and I'm truly grateful to you for that.

There is mention there of the banking security program TrusteerRapport causing problems with flash and I did have problems before with this program when Firefox updated to v.15 (though not with flash). I stopped Trusteer and my problem disappeared!

Once again thank you for your interest.

@JFFV - Which OS are you running/country are you in?

My version of Trusteer said no updates were available. I uninstalled it, downloaded a fresh copy and tried to install it but got an error message saying my system was not supported.

I'm in the UK, running Windows 8 Pro.
