Yeah, this is a known issue and sort of documented in the eDocs, but not clearly. Two hotfixes are required. Here's my documentation... :: For Windows 2003 and 2008R1 Citrix recommend installing the following two hotfixes mentioned in this :: security bulletin: http://www.microsoft.com/technet/security/bulletin/MS09-012.mspx :: One of the recommended hotfixes, KB956572, is already installed as a requirement for HDX MediaStream :: for Flash, so it's only the KB952004 that's really needed. Without them the UPM driver may fail to :: install during an upgrade and you'll get an error in the MSI logs such as "Unable to revert to a :: previous driver store for service 'upmjit'". This will cause a rollback of the upgrade process. A :: rollback in this case is not good, as by this time it has uninstalled the previous version too.
