I've just installed a new Citrix box and installed "Hotfix Rollup Pack 4 for Citrix XenApp 5.0 and Citrix Presentation Server 4.5 for Microsoft Windows Server 2003 32-bit Edition". I notice the hotfix panel in the Access Console shows loads of hotfixes against my other boxes but just this one patch against the new box. Are the patches cumulative so this latest patch is the only one required?
IIRC the rollup packs contain all the patches since the previous rollup pack so you need to install all of these. This is easiest done through Installation Manager (Enterprise upwards).
