Recently I had to work with version 11 of QTP. I ran into problems that I was not able to identify objects in Internet Explorer 8.
First thing I thought is, why IE8? But is was something the whole company still used. Although some people used the standalone version of Firefox.
Back to the problem. After searching the web i found the following link: http://sumitkumarshrivastava.blogspot.se/2012/10/qtp-11-error-not-able-to-identify-ie8.html.
Unfortunatly it was not possible to download the needed updates/patches directly. No username and password where available at that time. To solve this I used this: http://para.ms/index.php/locator/search/hpp/QTPWEB_00078 . At the end you place the patch that you want and open it in a browser. It does not work for all patches, but I was able to get the important ones and continue working with QTP 11.
