  • Hello,

    Crash info is not informative enough to find reason of crash.

    There are 3 possible ways to resolve this issue. I'm not sure which one resolve it.

    1. Try to suppress issue by switching OFF DEP for module crashed to BEX.

    - Right click on ‘My Computer’.
    - Go to ‘Properties’.
    - Click on ‘Advanced system settings’.

    - Under ‘Performance’ group, click ‘Settings’.
    - Click the “Data Execution Prevention’ tab.

    - Click ‘Turn on DEP for all programs and services except those I select’.
    - Click Add, browse to the executable file for the program (generally “C:\Program Files (x86)\HP\LoadRunner\bin\Wlrun.exe”) and add it.

    2. Modify script content, trying to find which property of script is reason of crash:

    - Try to play other type of scripts, TrueClinet or not;

    - Try to comment some parts of problematic script and then play it.

    This may show you a reason of problem. It may be type of script or specific command or group of commands. As result you may find workaround of problem or prove that Controller can’t play any type of script.

    3. Ask Support to create support case and escalate it to R&D. Escalated support case should contain full crash dump of Wlrun. exe. Please ask Support for help if you needed it to create crash dump.

  • thx.

    1. did already a bcdedit /set nx AlwaysOff... so dep is off. :)

    2. will try that, but simple http google script that searches a simple string in google also crashed 

    3. did this already. :)

  • I just had what appears to be the same issue.  After several days of trying anything, I reset all the controller options (Options window available in the Tools drop down menu) and the crashes stopped.

    I haven't bothered to tweak each of the options in turn until the crashing re-occurs but advise you try hitting all the default buttons on your scenario.


    Good luck,

  • Did you ever get a fix for this issue?  

    I currently am experiencing the same and also have DEP turned off, UAC Off, etc.  

    Upgrading to 12.53 makes controller work, but VuGen Records differently and doesn't work correctly - making 12.02 the best version - granted I can get controller to work.


    Thanks for any help you can provide.
