Suddenly LoadRunner 11.04 has stop recording our HTTPS web sites/pages. The Vugen 11.04 just hangers or the IE will open to a „Cannot This this page…“ error message.
Also notice it happen if we are recording a http site and move to a https page on the site. like the secure shopping cart page of the Site
It is odd because we did not make any changes to the LoadRunner
Please advise.
This is affecting LoadRunner Vugen versions 9 up to and including 11.5 that are trying to record secure sites (https:// www…). The problem is due to „Microsoft Security Update KB 2661254“ (Microsoft Security Advisory: Update for minimum certificate key length) now requiring 1024 bit RSA Certificates and LoadRunner Vugen currently uses 512 bit RSA Certificates . Please note HP is working on an update. In the mean time, there are two workarounds. The First workaround is to uninstall „Microsoft Security Update KB 2661254“ via the control panel add and remove Programs. (easiest) The second workaround is a registry edit adjusting the acceptable length of the certificate. Please see the article below For details of the registry edit as it varies from OS to OS.
For operating systems with Windows Vista. Windows 7 and Windows Server 2008, you can use certutil commands to change these registry settings. On Windows XP, Windows Server 2003, and Windows Server 2003 R2, you cannot use certutil commands to change these registry settings. However, you can use Registry Editor, reg command, or reg file.
At a CMD prompt type certutil -setreg chain\minRSAPubKeyBitLength 512
The „MinRsaPubKeyBitLength“ is a DWORD value that defines the minimum allowed RSA key length. By default, this value is not present, and the minimum allowed RSA key length is 1024. You can use certutil to set this value to 512 by running the above command:
