The answer to your question is ''Yes''. LoadRunner 12 TruClient does
support IE 11. You may want to consider upgrading as
LoadRunner 12.01 is the latest version. It is important to note
that it is recommended to turn off the Internet Explorer Enhanced
Security Configuration (IE ESC).

See how to turn off IE ESC for 2008 posted below:

* In the tree hierarchy, select ''Server Manager''
* The Server Summary will be displayed. Click on Configure IE ESC
* The Internet Explorer Enhanced Security Configuration dialog is displayed
* Make sure that the two off radio controls are selected
* Click the OK button.
