Setup Project shows ‘WARNING: Could not find prerequisite’ under Visual Studio 2010

Visual Studio Installer (MSI) warning:
WARNING: Could not find prerequisite '.NET Framework 2.0 (x86)' in path 'C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bootstrapper\'

or

WARNING: Could not find prerequisite '.NET Framework 2.0 (x86)' in path 'C:\Program Files\Microsoft SDKs\Windows\v7.0A\Bootstrapper\'

The result is that automatic downloading of prerequisites does not work any more. This is caused by fact, that Visual Studio 2010 does not include:

• .NET Framework 2.0
• .NET Framework 3.0
• .NET Framework 3.5 w/o SP1

There is discussion about this issue in VS2010 forum – Deployment project breaks on VS 2010 upgrade.

The suggested workaround is to use .NET Framework 3.5 SP1 Client Profile Prerequisite form available prerequisites under Setup project properties. This is some lightweight version of Microsoft .NET Framework.

If for some reason you do not want to use v3.5 framework, like, you do not want to force clients to download extra megabytes, you can copy needed Prerequisites from your Visual Studio 2008 folder.

From
"C:\Program Files (x86)\Microsoft SDKs\Windows\v6.0A\Bootstrapper\Packages\"
to
"C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bootstrapper\Packages\"
under x64 bit Windows, or if you have 32-bit Windows version, use the following path:
"C:\Program Files\Microsoft SDKs\Windows\v6.0A\Bootstrapper\Packages\"
to
"C:\Program Files\Microsoft SDKs\Windows\v7.0A\Bootstrapper\Packages\"

Folders:

• DotNetFX is .NET Framework 2.0
• DotNetFX30 is .NET Framework 3.0
• DotNetFX35 is .NET Framework 3.5 w/o SP1

P.S. Do not forget a proper testing!
