Abstract: HP Credential Manager for ProtectTools installs an Add-on for Internet Explorer that conflicts with certain Web pages
Submitted By: LANSA Technical Support


On some HP/Compaq notebook and tablet PCs where HP Credential Manager for ProtectTools is installed, invoking even the most simple WAM in Internet Explorer will cause IE to crash with the following screen:

Internet Explorer error

The error report indicates that the problem occurred in jscript.dll:

Internet Explorer error report

The WAM runs correctly in the Preview Window of the XSL Editor and (within functional limits) in other browsers such as Mozilla Firefox.


The cause of this issue has been traced down to an add-on to Internet Explorer which is installed by HP Credential Manager for ProtectTools. This add-on is known to conflict with certain Web pages. There are reports of similar problems with Web servers such as Microsoft Sharepoint Portal Server


Disabling the HP Credential Manager add-on in Internet Explorer resolves the issue. To do this you can use the following steps:

  1. Start Internet Explorer
  2. Select Manage Add-ons from the Tools menu
  3. In the Manage Add-ons dialog, click on HP Credential Manager for ProtectTools and then click Disable. Confirm your selection if asked.
  4. You may need to close all instances of Internet Explorer and restart for the change to take effect.
