Change the Local Installation Source After the Installation

When you deploy Microsoft® Office 2003 from the CD or from a compressed CD image on the network, Setup creates a local installation source in a hidden folder on each user’s computer. Windows Installer uses the local installation source to install Office, and the local installation source remains available so users can repair Office, install new features, and apply patches without being prompted for a CD.

Office 2003 Setup creates the local installation source on users’ computers based on options set by the administrator and on the amount of available hard disk space it detects on the default drive. By itself, Setup does not allow users to make many adjustments after the fact. But the new Local Installation Source Tool (LISTool.exe) provides more flexibility for managing the local installation source.


Toolbox    The Local Installation Source Tool (LISTool.exe) is available as a download. You can find this downloadable file on the Office 2003 Resource Kit Downloads page.


Using the Local Installation Source Tool, administrators can:

  • Disable the local installation source for users who are running short of hard disk space.
  • Move the local installation source to a different drive.
  • Enable the local installation source after Office is installed.

 Note    You must be the administrator of the local computer to run the Local Installation Source Tool. If you are an administrator in a large organization, you can write a script that runs the Local Installation Source Tool quietly on users’ computers.


Deleting and disabling the local installation source

Providing users with a local installation source gives them great advantages when it comes to performing any operations that require the source, such as updating their applications and installing new features. However, a complete local installation source does require about 300 megabytes (MB) of hard disk space. If you deploy Office with a local installation source and then discover that some users are running low on hard disk space, you can disable and delete the local installation source for only those users with the Local Installation Source Tool.

Even if those users chose the option to delete the local installation at the end of Setup, or if they manually delete the Msocache folder, the local installation source is not completely disabled. If Office is deployed with the local installation source enabled, then Setup will recreate the Msocache folder when necessary. In order to completely delete and disable the local installation source, you need to select the Delete and disable LIS option in the Local Installation Source Tool and then run it on users’ computers.

Moving the local installation source to a different drive

Although you can specify a location for the local installation source when Office is first installed, you cannot change the location of the local installation source later on by moving the Msocache folder. However, the Local Installation Source Tool allows you to move the local installation source to a different drive — for example, a new hard disk drive with more free space — with the following caveats:

  • You must move the local installation source to the root of the new drive.

This requirement helps enhance security, since it locks write access to the folder to everyone except the administrator.

  • You must move the entire local installation source, which includes source files for all Microsoft Office System applications.

Office Setup does not support spreading the local installation source over multiple drives.

When you select the Move the LIS to a different drive option in the Local Installation Source Tool, it displays the available hard disk drives and indicates how much disk space is required and how much is available. If a particular drive has insufficient disk space, the Local Installation Source Tool does not present it as an option. In addition, an NTSF-formatted hard disk drive is recommended over a FAT-formatted drive. Windows Installer is directed to use this location as its primary source from this point on.


 Note   Moving the LIS to a different hard disk drive does not create a complete local installation source if it was missing or incomplete in the original location. The option to move the LIS only changes settings in the Windows registry to redirect the existing source files to the new location. If you want to rebuild a complete LIS, then you must run the tool a second time and select the Enable LIS option, as described in the following section.


Enabling the local installation source

Up to now, if you did not install Office with a local installation source to begin with, or if users deleted the local source, you could not add one after the fact. The Local Installation Source Tool allows administrators to create a complete local installation source on users’ computers after Office is installed, provided the initial installation was performed from a compressed source.

You can use the Local Installation Source Tool to recreate a local installation source if it was manually deleted, or you can install a complete local installation source if you initially installed with a partial source. You can also choose to create a local installation source for individual Office 2003 editions — only Office 2003 Professional Edition, for example, but not Microsoft Office Visio 2003. Windows Installer is redirected to use the local source as its primary source from that point on.

When you select the Enable LIS option in the Local Installation Source Tool, keep in mind the following points:

  • You cannot create a local installation source if you deploy Office from an uncompressed administrative image.
  • All the hard disk space requirements for installing a local installation source in the first place apply to creating it after the fact. For example, Setup must detect at least 2.5 gigabytes (GB) of free hard disk space on the drive before it will install a complete local installation source.
  • Users will need access a compressed source in order to create the local installation source. The Local Installation Source Tool will prompt them for the Office 2003 CD or a path to a network source. After that, however, users will be able to rely on the local installation source instead.
  • The option in the Local Installation Source Tool overrides the option to clean up the local installation source by using the Disk Cleanup Wizard.

The following table defines the command-line options that you can use with LISTool.exe; you can also view these options by typing /? at the command line.

Option Definition
/q Display no user interface (quiet mode).
/qb Display only simple progress indicators and error messages (basic mode).
remove Set to all to disable and delete the local installation source. You can also set this property to the product code for the package you are deploying.
move=drive Move the local installation source to the specified drive.
enable Set to all to enable the local installation source. You can also set this property to the product code for the package you are deploying.
sources=path Specify the source list when enabling the local installation source.
