LoadRunner Citrix registry patch issue

I am facing recording issues in Loadrunner while trying to use SAP web + citrix protocol combination.

·         First, I use VuGen from my local machine and connect to Citrix gateway link

·         Once I are into this Citrix box, I connect to SAP CRM  via the same Citrix gateway link.

·         Tried in LR version 12.01, IE10 and Citrix Receiver version is 4.1.

·         Initially while trying to record, the citrix ICA is getting opened and showing “Unsupported function”;

·         Now I am getting the registry error. 'Load Runner needs to install a Citrix registry patch to record on this version of citrix client.'

 I  click on OK but then the IE dows not open at all.

·         Tried in LR version 11.52, IE10 and Citrix Receiver version is 4.1. Here I am not getting any error, but the citrix events are not getting captured.

Need you suggestion urgently.
