Denali Setup fails reporting NoRebootPackageDownLevel is found on “Vista/Windows Server 2008” failed

If you are running your server on dot net framework 3.5 SP1 (this is minimum framework version you will need to install Denali), then you may face an error as below which will prevent you from installing Daneli (possibly SQL 2011).

NoRebootPackageDownLevel This rule determines whether the computer has the required update package that ensures that the computer will not have to be rebooted because of the Microsoft .NET Framework 4 installation. Failed This computer does not have the update package that ensures that the computer will not have to be rebooted because of the Microsoft .NET Framework 4 installation. Before setup is allowed to proceed, download and install the required update package from: http://go.microsoft.com/fwlink/?LinkID=195093. After you install the update package, the computer will require a reboot.

Solution of this problem is to install a simple fix from http://go.microsoft.com/fwlink/?LinkID=195093 which must be applied after dotnet framework 3.5 SP1. Alternately you can directly go to http://www.microsoft.com/downloads/en/details.aspx?FamilyID=74a30045-74b5-4165-8917-b65e5ebd8902&displaylang=en and download appropriate update based on your server and install it. This will immediately fix the issue.

Note:

This update is required as it is a known issue with the Microsoft .NET Framework 3.5 Service Pack 1.

This update will not require any reboot.
