When you try to install an update for Microsoft Visual Studio .NET 2002, you may receive an error message that resembles the following:
The feature you are trying to use is on a network resource that is unavailable.
Click OK to try again, or enter an alternate path to a folder containing the installation package File_name .msi in the box below.
Updates for Visual Studio are based on Windows Installer. Windows Installer uses file version numbers to determine whether a file on a computer is an older version that must be replaced by a newer file that is contained in an update.
Certain files, such as text files and source files, do not carry version numbers. Therefore, the Windows Installer-based update must use another method to verify newer files. This method uses a hash for all non-versioned files. For non-versioned files, the file hash of the file on the computer is compared with the file hash that is recorded in the Windows Installer database. If a difference is detected between these two file hashes, Setup tries to fetch the file from the source installation media.
To work around this issue, insert the product installation CD in the computer's CD ROM drive. Or, provide the path of the available installation media for the product. For example, the installation media may be available on the computer's hard disk or in a shared network folder.
The "/addsource" command-line optionIf you are trying to deploy an update to lots of computers on which this issue may occur, we recommend that you first use the /addsource command-line option if this option is available.
