VB6RunTime.nsh

Setup of Visual Basic 6.0 run-time files, including the Oleaut32.dll security update

Copyright 2008-2017 Joost Verburg

To obtain the run-time files, download and extract
http://nsis.sourceforge.net/vb6runtime.zip

Script code for installation:

!insertmacro InstallVB6RunTime FOLDER ALREADY_INSTALLED

in which FOLDER is the location of the run-time files and ALREADY_INSTALLED is the
name of a variable that is empty when the application is installed for the first time
and non-empty otherwise

Script code for uninstallation:

!insertmacro UnInstallVB6RunTime

Remarks:

* You may have to install additional files for such Visual Basic application to work,
  such as OCX files for user interface controls.
  
* Installation of the run-time files requires Administrator or Power User privileges.
  Use the Multi-User header file to verify whether these privileges are available.

* Add a Modern UI finish page or another check (see IfRebootFlag in the NSIS Users
  Manual) to allow the user to restart the computer when necessary.
