VSI Installation Issue
July 1, 2008

Some readers have reported errors when trying to install the chapter-specific
templates through the download source code's "VSI" file. When double-clicking
on the "Programming Visual Basic 2008 Templates .VSI" file, the following
error may appear on some systems:

   One or more content items contained within the .vscontent file cannot be
   installed because the correct version of the content installer component
   cannot be found.

   Contact the author of the content file for information about which installers
   and versions are required.

Microsoft has confirmed that this is caused by a problem with the installation
of Visual Basic 2008 Express Edition. The problem appears in the original
release of that product, and in the beta version of the SP1 release for that
product. It is unclear at this time whether it will be fixed before the official
release of Visual Basic 2008 Express Edition SP1.

Microsoft has provided a temporary workaround for this issue. They have written
a "Registry Script" file (with a .REG extension) that can be used to correct the
system registry issues caused by the faulty installation. To access this file,
visit the publisher's web site for this book:

Use the menu on the left side of this page to access the "Examples" link. On
the listing of files that appears, you will see one file with the name:

   Fix - VB2008 Express VSI Issue.reg

Download this file to your workstation. The file is designed to fix systems
that have installed Visual Basic 2008 Express Edition in its standard install
location. If you used a custom install location, you must edit this file using
Notepad before processing it.

To process the file, double-click on it. You will be prompted to confirm the
update to the registry. Respond by clicking on the "Yes" button. Once the update
is installed, you should be able to complete the VSI installation without error.
