Avoiding .NET framework 4.0 reboot at the end of installation setup

Question

Hi

We have a requirement to avoid reboot during installation.

I have two question regarding .NET framework installation without reboot at the end:

1. Which OS demand reboot at the end of .NET framework installation (I tried it on Windows Server 2008 with SP1-NO reboot has been required, while on Windows Server 2008 without SP1-reboot has been required).

We needs to support Win2003 R2 SP2, Win2008 R2 SP1, Vista SP2, Win7 SP1

2. If we use the /norestart switch for the setup.exe, does my program that uses .NET 4.0 parallel extentions can run without problems?

Thanks,

Michal

Hi MMM11,

Welcome to the MSDN forum.

I think you can refer to this blog http://blogs.msdn.com/b/astebner/archive/2006/06/13/627729.aspx

Your issue is more related to why we need a reboot when deploy .NET Framework and "How to manage reboots when deploying the .NET Framework".

"When does .NET Framework setup require a reboot?
The .NET Framework setup will require a reboot when one of the files it needs to install is in use during installation.  There are a handful of files that are shared by all versions of the .NET Framework, so if there is an earlier version of the .NET Framework installed on the system than the one that is currently being installed, and a managed application is running and holding one of the shared files in use, then a reboot could be required at the end of installation."

As for how to manage, you can refer to "How can I tell if .NET Framework setup requires a reboot?" and the other instructions.

Best regards,
