LoadRunner and IE8

Had this small problem today and I believe it would be interesting to share the solution. I was “forced” to update to Internet Explorer 8 (IE8) and for my surprise, VuGen crashes when trying to record anything with it.

My first thought was to check for patches. No patches, LoadRunner was already on version 9.52 (9.50 + 9.51 patch + 9.52 patch). Checking some forum posts I’ve found that the issue can be caused by the “Disable Execute Bit” (DEP) functionality. So how to disable it??

You have to open the boot.ini file (C:\boot.ini) and add the following string to your boot line:


Usually it will become something like that:

multi(0)disk(0)rdisk(0)partition(1)\WINNT=”Microsoft Windows” /noexecute=alwaysoff /fastdetect

I’m not sure if the same solution can be applied to Windows Vista or 7. Also I don’t know if older LoadRunner versions are affected too, but this worked for me. :-)

  1. Thank you Martin

    Was having all sorts of problems with DEP and crashes with VUGEN. Never had it before – but then I’ve never had IE8 pushed onto me before.

    Keep up the good work!

    • Thanks Justin!
      Shamefully I did not have much time to write or reply to comments on the blog lately, but I hope to change that in the near future.


  2. I’ve installed a new copy of LoadRunner 11 with the provided license and it works fine with Virtual User Generator and Analysis but when i try to open the Controller it says “License Security Violation. Operation is Not Allowed”. I tried to contact the HP support but there was no timed response. How can i fix this?, Does this mean my registry is corrupted?. Should i re-install the Operating System?, FYI it’s an 32 bit Operating System.

    • Hi Jake,
      That usually happens when there is something wrong with the license key that you used. I’ve seen problems with HP sending out wrong license keys (for different products, temporary instead of permanent licenses, etc) before.
      On previous versions, I’ve seen problems with LR messing with the License Keys on the registry, but that is not the case anymore with LR 11. So no need to re-install anything.
      The best alternative would be to contact HP’s support to get that figured out. In most cases they reply pretty quickly.


  3. Hello,

    I have some information that may be interesting…
    IE 8 is not supported by LR9.5x and previous versions. In some cases it may work, but some cases it may not.
    DEP blocks the scripting (it’s a security setting in Windows), so no matters which version of LR you have, DEP must be disabled.

    There is a betta patch for supporting IE8, even when it is not supported, seems to work in most of the cases. You can ask the HP LR support team for this patch.

    Also, as you should know, LR11 was released 2 weeks ago, and it supports IE8.

    Hope this helps.


    • Hi Marcos,
      Thanks for your input. The HP rep that I spoke with at the time said that there was no patch for LR 9.5 that would solve that, but you know how they are ;-)
      This workaround worked pretty well so far and I never had issues with it, but having a native support is always better..

      I have not tested LR 11 yet, but I’ve been hearing good things about it.. If you already have it and want to share your first impressions, let me know.
