How to use the "File Check" option of BMG(BOOTSTRAPPER MANIFEST GENERATOR) tool to check if the preRequisite is already installed on the system?

Hi I am using BMG (Bootstrpper Manifest Generator) tool to pa开发者_StackOverflow社区ckage a custom "PREREQUISITE" application, which can be installed prior to installation of a set up project application. But I want to check if the prerequisite application already exists or not before beginning the installation.

It dawned on me that this can be achieved by using "File Check" option in BMG(Bootstrapper Manifest Generator). CAN ANYONE KINDLY LET ME KNOW HOW TO USE THE FILE CHECK OPTION OF "BMG TOOL".

Thanks In Advance.

The way I use it for Acrobat Reader X:

• go to the System Checks tab.
• click the File Check button.
• In "Property For Result", put an explanatory name (ex: 'AcrobatReader')
• In "File name to search for", put the name of the main executable file of the prerequesite application (ex. for Acrobat Reader: 'AcroRd32.exe').
• Optionally, check "Start Search in Special Folder", and select "ProgramFilesFolder" (supposing the prerequesite installs there).
• If you check it, put in Path the subfolder in wich the prerequesites is installed (ex. for Acrobat Reader: Adobe\Reader 10.0\Reader)
• In Search Depth, put 0 if you want to search in every subfolder, or any number if you want to stop at a certain depth. 0 by default.
• Go to the Install Conditons tab.
• In the first line, column Type, choose ByPassIf
• column Property, choose the name of your previously created Property For Result (in this case, AcrobatReader).
• in the third column, choose 'Exists'.

You can also do something equivalent for registry keys, check versions...
