Openscript installation error WebDom Browser Helper Installation failed

Like Tweet Pin it Share Share Email

When trying to install openscript some times we see an issue like WebDom Browser Helper installation failed! Failed to unregister OpenScript IEToolbar  DLL, as shown in the below image.

WebDom Browser Helper Installation failed

Troubleshooting can be done by performing below steps one after the other and it might get resolved at one place:

Step 1:

Click OK and continue the installation, we may see above popup appearing multiple times during the installation process, we just need to click OK and continue to finish the installation process.

  • Close all your IE browsers if any are opened.
  • Run the uninstall browser helper by executing below command in Command prompt C:\OracleATS\OpenScript\UninstallBrowserHelpers
  • Delete the existing folder C:\OracleATS\OpenScript\Oracle IE toolBar
  • Reinstall the browser helpers by executing below command in Command Prompt C:\OracleATS\OpenScript\InatallBrowserHelpers

In case this does not help, you can try step 2 and perform re perform step 1.

Step 2:

  • Navigate to services panel, give services.msc command in windows run
  • Look for Helper service of Oracle Applicaiton Testing Suite
  • Open properties window by right clicking on the service and select Log On Tab
  • Specify an interactive user who can run the Openscript and Click OK
  • Restart service by right clicking the service and selecting the “Restart” menu item.

Note: Repeat the above steps for “Oracle Application Testing Suite Agent Service”

In case if it still doesn’t work final solution would be to reinstall openscript.

            Hi Risbhah,

            Thank you for reaching out to us on this.

            I am sure, we can automate JDE application using OATS, but when you say JDE mainframe, I want to see what exactly they are ? how do you use them exactly and where do you get the response etc..

            may be if you can send some steps, screenshots, and other details to testingtools.co@gmail.com I can try my best to come back on it.

            Thank You,

      Is this a fresh install or a fresh install on this machine / laptop ?

      If it is not a fresh install, I would recommend you to do a clean uninstall of Oracle Application Testing Suite ( a.k.a OATS ) and then install OATS with elevated privileges. I am sure you are aware of it.

      Before installing OATS , please verify if Chrome version is compatible, which otherwise please have the compatible Chrome version and proceed with installation.

  • Hi Srinivas,
    I have uninstalled the prev version of OATS and followed all the steps from your article. While installing itself, i am getting the failure “Openscript installation error WebDom Browser Helper Installation failed” and showing “can not save multiple user execution settings for chrome native host in registry under key”hklm\software\google\chrome\nativemessaginhosts\oracle.openscript.hosts”.

    I have uninstalled the chrome and tried installing openscript but while re-installign itself i am getting this error.

  • Hi Srinivas,

    1. Resintaling the Browser helpers .
    2. Changing the permissions for Helper and Agent in services .
    3. Reinstalling the Openscript
    I have done the steps 1 , 2 and 3 , but still I am getting the same error “Can’t enable IE toolbar”.
    What might be the reason ?

  • Hi Srinivas,

    Im getting Incompatible Addons for IE11 after installation of OATS 13.1 Please Help me on this.

      Hi Ajay,

      Thank you for reaching out to us, Some times you may have to uninstall OATS and when installing OATS you have to run the setup file with Run As Administrator option.
      If this does not work, you may have to uninstall the browser helpers and then install again as described in the article.

      In case it doesn’t work still, it would be great if you can either create a video or come on a screen share. to see if it can be resolved.

      Thank You,
      Srinivas P.
