When you try to install Microsoft Visual Studio .NET or Microsoft Visual Studio 2005, you may receive the following error message:
Setup has detected that another program requires the computer to reboot. You must reboot the computer before installing Visual Studio .NET Prerequisites. Once the system reboots, you need to restart setup. Click OK to reboot. Click Cancel to exit setup and install later.
When you run a Setup program to install any application, Setup may try to update some files that your operating system is currently using. For example, Setup may try to rename or to delete these files. If Setup cannot update these files, Setup sets the
registry entry to a non-empty value. You must manually restart your computer to update the files that your operating system was using during the installation process.
If you do not restart your computer, these files are not updated. If you then try to install another application (such as Visual Studio .NET), Microsoft Windows Installer determines that the
registry entry is not empty. Therefore, you receive the error message that appears in the "Symptoms" section of this article.
To resolve this problem, use any one of the following methods:
Restart your computer, and then run the Visual Studio .NET or Visual Studio 2005 Setup program.
Run the Setup program that is included on the Windows Component Update CD instead of the Setup program that is included on Visual Studio .NET CD1 or Visual Studio 2005 CD1. After Windows Component Update has completed, run the Visual Studio .NET or Visual Studio 2005 Setup program that is included on CD1.
Prevent your computer from restarting by removing registry information about packages that require your computer to restart. To do this, follow these steps.
