如何提示用户重新安装.NET？

Question

I'm using Visual Studio 2008 to write an installation, and I'm a completely new to installations. I've created an installation and successfully written some custom actions using a C# assembly. One action sets a RunOnce registry value, and now I need to prompt the user to reboot when the installation finishes, but I have no idea how. I've read the Installer class documentation, but I can't find any mention of rebooting.

I'm assuming I need to somehow get down to being able to call MsiSetProperty and set a REBOOT property, but I don't know how to do that from my .NET installer project.

Answer 1

Thanks. I ended up using a post-build event to run a batch file with the following command. The hard part was tracking down WiRunSQL.vbs, which was in the "Windows SDK Components for Windows Installer Developers" download.

cscript "C:\Program Files\Microsoft SDKs\Windows\v6.0\Samples\SysMgmt\MSI\scripts\WiRunSQl.vbs" my.msi "INSERT INTO `Property`(`Property`, `Value`) VALUES ('REBOOT', 'F')"

If you are implementing your installer using WiX , you need to add this:

<ScheduleReboot After="InstallFinalize"/>

If you're using the cut-down "Installer" project in Visual Studio , I'm not sure... But this link here suggests a CScript command that seems to show how to inject an MSI property into the installer project, much as you want to do.

Answer 3

Just set the property in the MSI initally, rather than trying to update it at runtime.

Visual Studio 2008 ships with WiX anyway, see Visual Studio ships the WiX toolset for more details. That said, I'm not a Visual Studio 2008 user, so I don't know if that's in addition, or in replacement to the previous Visual Studio setup projects.
