Thanks for the interesting question indeed!
Hotfix distributions are the smallest set of files, needed for the full operation of a project utilizing RadControls. I would suggest that you don't replace the original installation files with the ones from the hotfix, as this could potentially leave the installer in a broken state (the least that could happen are remaining assemblies after uninstall).
Telerik distribute MSI packages for each official release (be it a major release, or a service pack). The MSI installers of the minor releases (service packs) perform an update over their predecessors (e.g. Q1 2011 SP2
will automatically update Q1 2011
or Q1 2011 SP1
). We prefer not to use the msp approach, for we would need to create msp files for every combination of update paths. That might get too confusing for customers to follow.
We just chose the make it easier for our customers, though this is related to downloading some more megabytes.
As a side note, I would suggest that you use the VSExtensions
. They automatically discover new updates, suggest downloading the hotfix files to your computer and list them in the Upgrade Wizard. You can use the Upgrade Wizard to update the references of your project to a newer/older version of the RadControls.
Let me know if I can be of any other help.
