How to access an opened application by giving commands to it?

[kimhyun]

I have to install an application(.exe file) using commands from labview instead of doing it manually. Is it possible?

Use the "system exec" function in labview to run the installer from a command line.

msiexec should do the trick.  But it totally depends on the application you are installing.  Here is an example:

You could compile your own labview VI into an EXE and build an installer for it.  Then you can call third party installers from there.
