Support for Windows Vista Service Pack 1 (SP1) ends on July 12, 2011. To continue receiving security updates for Windows, make sure you're running Windows Vista with Service Pack 2 (SP2). For more information, refer to this Microsoft web page: Support is ending for some versions of Windows
(http://windows.microsoft.com/en-us/windows/help/end-support-windows-xp-sp2-windows-vista-without-service-packs)
.
This problem occurs because of a design change in Windows
Server 2008 and in Windows Vista SP1. The Citrix application installer tries to modify the values of some registry subkey entries. However, Windows Resource Protection (WRP) provides enhanced protection for these registry subkey entries, and only the TrustedInstaller group can modify the entries.
