Each time I restart computer & run Norton System Works One Button Checkup, it
finds same problems: missing program files: i.e.:
....NET\FRAMEWORK\v2.0...cannot access a necessary file, "msvcr80.dll". I
have .net framework 1.1, .net framework 1.1 hotfix (KB886903), and .net
framework 2.0 installed. I would like to know how to correct the missing
(msvcr80.dll) file problem.

This is because the installer for VS.NET 2005 puts unmanaged shared DLLs
in the WinSxS side-by-side cache, and not in %windir%\System32. In a
brilliant flash of inspiration Microsoft decided to call the deployment
unit for shared DLLs a 'shared assembly' and the information that
describes what files that are in such a side-by-side shared assembly
they call a manifest. msvcr80.dll is in a side-by-side assembly called
Microsoft.VC80.CRT, you'll find the DLL under a folder that has this
assembly name in its name under %windir%\WinSxS.

An application that uses a DLL in a side-by-side assembly must have an
application manifest that says the assembleis it uses. If you don't have
an application manifest file (app.exe.manifest for app.exe) then you'll
get the error you mention.

Such a manifest can come through the application manifest file, or if
the module that uses the assembly DLL is itself a DLL then it can be XML
embedded in that DLL.
