Do I Need Msvbvm50.exe?
Msvbvm50.exe is not intended to replace the Setup Wizard for
distributing Visual Basic applications. For example, if your application
includes components, such as ActiveX controls or DLLs, you should use the
Application Setup Wizard or a third party setup package for distribution.
However, if your Visual Basic application only depends upon the files included
in Msvbvm50.exe, you can distribute your application by providing end users
with the executable (.exe) file and Msvbvm50.exe.
whether your application requires additional files for distribution, you can
use the Setup Wizard to create a set of setup files as a test. If the [Files]

fails during Setup, the core files on the target computer may be mismatched. If
the versions of the files in Msvbvm50.exe are newer than the versions on the
target computer, running Msvbvm50.exe before running Setup may resolve the
